rework this to actually generate from the top-level.
This currently builds off of the objects that go into the libsim.a as
we don't build those from the top-level either. Once we migrate that
up, we can switch this to the source files directly. It's a bit hacky
overall, but makes it easier to migrate things in smaller chunks, and
we aren't going to keep this logic long term.

gdb/linespec.c: Fix missing source file during breakpoint re-set
During breakpoint re-setting, the source_filename of an
explicit_location_spec is used to lookup the symtabs associated with
the breakpoint being re-set. This source_filename is compared with each
known symtab filename in order to retrieve the breakpoint's symtabs.
However the source_filename may have been originally copied from a
symtab's fullname (the path where GDB found the source file) when the
breakpoint was first created. If a breakpoint symtab's filename and
fullname differ and there is no substitute-path rule that converts the
fullname to the filename, this will cause a NOT_FOUND_ERROR to be thrown
during re-setting.
Fix this by using a symtab's filename to set the explicit_location_spec
source_filename instead of the symtab's fullname.

gdb/c++: Detect ambiguous variables in imported namespaces
When running gdb.cp/nsusing.cc and stopping at line 17, we can ask GDB
to print x and get a compiler-dependent answer. Using gcc 12.2.1, GDB
will print M::x, and using clang 16.0.0 prints N::x. Not only is this
behavior confusing to users, it is also not consistent with compiler
behaviors, which would warn that using x is ambiguous at this point.
This commit makes GDB behavior consistent with compilers. it achieves
this by making it so instead of exiting early when finding any symbol
with the correct name, GDB continues searching through all include
directives, storing all matching symbols in a relational map betwen the
mangled name and the found symbols.
If the resulting map has more than one entry, GDB says that the
reference is ambiguous and lists all possibilities. Otherwise it returns
the block_symbol structure for the desired symbol, or an empty struct if
nothing was found.
The commit also changes gdb.cp/nsusing.exp to test the ambiguous
detection.

gdbsupport: fix scoped_debug_start_end's move constructor
I spotted a problem with scoped_debug_start_end's move constructor.
When constructing a scoped_debug_start_end through it, it doesn't
disable the moved-from object, meaning there are now two objects that
will do the side-effects of decrementing the debug_print_depth global
and printing the "end" message. Decrementing the debug_print_depth
global twice is actually problematic, because the increments and
decrements get out of sync, meaning we should hit this assertion, in
theory:
gdb_assert (debug_print_depth > 0);
However, in practice, we don't see that. This is because despite the
move constructor being required for this to compile:
template<typename PT>
static inline scoped_debug_start_end<PT &> ATTRIBUTE_NULL_PRINTF (6, 7)
make_scoped_debug_start_end (PT &&pred, const char *module, const char *func,
const char *start_prefix,
const char *end_prefix, const char *fmt, ...)

va_list args;
va_start (args, fmt);
auto res = scoped_debug_start_end<PT &> (pred, module, func, start_prefix,
end_prefix, fmt, args);
va_end (args);
return res;
}
... it is never actually called, because compilers elide the move
constructors all the way (the scoped_debug_start_end gets constructed
directly in the instance of the top-level caller). To confirm this, I
built GDB with -fno-elide-constructors, and now I see it:

fine because we never free gdbarch objects, and thus we never free
gdbarch_tdep objects. There is an exception to that however: when
initialization fails, we do free the gdbarch object that is not going to
be used, and we free the tdep too. Currently, i386 and s390 do it.
To make things clearer, change gdbarch_alloc so that it takes ownership
of the tdep. The tdep is thus automatically freed if the gdbarch is
freed.
Change all gdbarch initialization functions to pass a new gdbarch_tdep
object to gdbarch_alloc and then retrieve a non-owning reference from
the gdbarch object.
Before this patch, the xtensa architecture had a single global instance
of xtensa_gdbarch_tdep. Since we need to pass a dynamically allocated
gdbarch_tdep_base instance to gdbarch_alloc, remove this global
instance, and dynamically allocate one as needed, like we do for all
other architectures. Make the `rmap` array externally visible and
rename it to the less collision-prone `xtensa_rmap` name.

gdb: use libbacktrace to create a better backtrace for fatal signals
The code is trying to select between using libbacktrace or using the
execinfo supplied backtrace API.
First we check to see if we can use libbacktrace. If we can then we
include some header files, and then set some defines to indicate that
libbacktrace is being used.
Then we check if execinfo is available, if it is then we include
<execinfo.h> and set some alternative defines.
In theory the second block of logic should not trigger if the first
block (that uses libbacktrace) has also triggered, but we incorrectly
check the define 'PRINT_BACKTRACE_ON_FATAL_SIGNAL' instead of checking
for 'GDB_PRINT_INTERNAL_BACKTRACE_USING_LIBBACKTRACE', so the second
block triggers more than it should. The
'PRINT_BACKTRACE_ON_FATAL_SIGNAL' define is not defined anywhere, this
was a mistake in the original commit.
In reality this is harmless, we include <execinfo.h> when we don't
need too, but in by-utils.c the libbacktrace define is always checked
for before the execinfo define, so we never actually end up using the
execinfo path (when libbacktrace is available). But I figure its
still worth cleaning this up.
I've tested GDB in a "default" build where libbacktrace is used, and
when configuring with --disable-libbacktrace which causes the execinfo
backtrace API to be used instead, both still appear to work fine.
There should be no user visible changes after this commit.

Avoid unaligned pointer reads in PEP .idata section
This is something I discovered when working on aarch64, though it's
relevant to x86_64 too.
The PE32+ imports are located in the .idata section, which starts off
with a 20-byte structure for each DLL, containing offsets into the rest
of the section. This is the Import Directory Table in
https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, which
is a concatenation of the .idata$2 sections. This is then followed by an
20 zero bytes generated by the linker script, which calls this .idata$3.
After this comes the .idata$4 entries for each function, which the
loader overwrites with the function pointers. Because there's no padding
between .idata$3 and .idata$4, this means that if there's an even number
of DLLs, the function pointers won't be aligned on an 8-byte boundary.
Misaligned reads are slower on x86_64, but this is more important on
aarch64, as the e.g. `ldr x0, [x0, :lo12:__imp__func]` the compiler
might generate requires __imp__func (the .idata$4 entry) to be aligned
to 8 bytes. Without this you get IMAGE_REL_ARM64_PAGEOFFSET_12L overflow

gdbarch_return_value only accepts a buffer as an out parameter.

After an attempt at this, I realized I wouldn't be able to correctly
update all implementations (there are ~80) of this method. So,
instead, this patch adds a new method that falls back to the current

sim: build: add var for tracking sim enable directly
Rather than rely on SIM_SUBDIRS being set, add a dedicated variable
to track whether to enable the sim. While the current code works
fine, it won't work as we remove the recursive make logic (i.e. the
SIM_SUBDIRS variable).

sim: common: drop libcommon.a linkage
All of these objects should be in libsim.a already, so don't link to
it too. In practice it never gets used, but no point in listing it.

sim: build: move generated headers to built sources
Automake's automatic header deptracking has a bootstrap problem where
it can't detect generated headers when compiling. We've been handling
that by adding a custom SIM_ALL_RECURSIVE_DEPS variable, but that only
works when building objects recursively in subdirs. As we move those
out to the top-level, we don't have any recursive steps anymore. The
Automake approach is to declare those headers in BUILT_SOURCES.
This isn't completely foolproof as the Automake manual documents: it
only activates for `make all`, not `make foo.o`, but that shouldn't be
a huge limitation as it only affects the initial compile. After that,
rebuilds should work fine.

sim: cgen: drop common subdir build rules
Now that everything has been hoisted to the top-level, we can delete
this unused logic.

sim: cgen: hoist rules to the top-level build
The rules seem to generate the same output as existing subdir cgen
rules with cgen ports, so hopefully this should be correct. These
are the last set of codegen rules that we run in subdirs, so this
will help unblock killing off subdir builds entirely.

sim: build: use Automake include vars
Rather than define our own hack for emitting an include statement,
use the existing Automake include variables. These have the nice
side-effect of being more portable.
