[gdb/testsuite] Fix gdb.threads/dlopen-libpthread.exp for upstream glibc, again
On an x86_64 laptop running ubuntu 22.04.1 with unity desktop:
...
$ echo $XDG_CURRENT_DESKTOP
Unity:Unity7:ubuntu
...
I have:
...
$ echo $LD_PRELOAD
libgtk3-nocsd.so.0
...
due to package gtk3-nocsd, a package recommended by unity-session.
Consequently, for each exec these dependencies are pulled in, including
libpthread.so.0:
...
$ lddtree /lib/x86_64-linux-gnu/libgtk3-nocsd.so.0
libgtk3-nocsd.so.0 => /lib/x86_64-linux-gnu/libgtk3-nocsd.so.0 (interpreter => none)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6
ld-linux-x86-64.so.2 => /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
...
So, while test-case gdb.threads/dlopen-libpthread.exp appears to run ok:
...
# of expected passes 12
# of unsupported tests 1
...
with LD_PRELOAD="" we have instead:
...
(gdb) PASS: gdb.threads/dlopen-libpthread.exp: continue to breakpoint: notify

$hex $hex Yes /lib64/ld-linux-x86-64.so.2^M
$hex $hex Yes /lib/x86_64-linux-gnu/libc.so.6^M
$hex $hex Yes dlopen-libpthread.so^M
(gdb) FAIL: gdb.threads/dlopen-libpthread.exp: libpthread.so found
...
The problem is that libpthread is expected as dependency of
dlopen-libpthread.so, but it's missing:
...
$ lddtree dlopen-libpthread.so
dlopen-libpthread.so => ./dlopen-libpthread.so (interpreter => none)
libc.so.6 => $outputs/gdb.threads/dlopen-libpthread/dlopen-libpthread.so.d/libc.so.6
ld-linux-x86-64.so.2 => /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
...
due to having glibc 2.35, which has libpthread integrated into libc.
Fix this by:
- adding a proc has_dependency
- using [has_dependency $exec libpthread.so] as hint that libpthread
may be preloaded
- using ![has_dependency $shlib libpthread.so] to detect that
the libpthread.so dependency is missing.
Also add a missing return after untested "no matching probes".
Tested on x86_64-linux, with and without LD_PRELOAD="".

gas/RISC-V: adjust assembler for opcode table re-ordering
PR gas/29940
With the single-operand JAL entry now sitting ahead of the two-operand
one, the parsing of a two-operand insn would first try to parse an 'a'-
style operand, resulting in the insertion of bogus (and otherwise
unused) undefined symbols in the symbol table, having register names.
Since 'a' is used as 1st operand only with J and JAL, and since JAL is
the only insn _also_ allowing for a register as 1st operand (and then
there being a 2nd one), special case this parsing aspect right there.

gdb/dwarf2: Fix 'rw_pieced_value' for values casted to different type.
The 'rw_pieced_value' function is executed when fetching a (lazy)
variable described by 'DW_OP_piece' or 'DW_OP_bit_piece'. The
function checks the 'type' and 'enclosing_type' fields of the value
for identity.
* The 'type' field describes the type of a value.
* In most cases, the 'enclosing_type' field is identical to the
'type' field.
* Scenarios where the 'type' and 'enclosing_type' of an object
differ are described in 'gdb/value.c'. Possible cases are:
* If a value represents a C++ object, then the 'type' field
gives the object's compile-time type. If the object actually
belongs to some class derived from `type', perhaps with other
base classes and additional members, then `type' is just a
subobject of the real thing, and the full object is probably
larger than `type' would suggest.
* If 'type' is a dynamic class (i.e. one with a vtable), then GDB
can actually determine the object's run-time type by looking at
the run-time type information in the vtable. GDB may then elect
to read the entire object.
* If the user casts a variable to a different type
(e.g. 'print (<type> []) <variable>'), the value's type is
updated before reading the value.
If a lazy value is fetched, GDB allocates space based on the enclosing
type's length and typically reads the 'full' object. This is not
implemented for pieced values and causes an internal error if 'type'
and 'enclosing_type' of a value are not identical.
However, GDB can read the value based on its type. Thus, this patch
fixes the previously mentioned cases by removing the check for identity.

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

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.
