x86: re-work ISA extension dependency handling
Getting both forward and reverse ISA dependencies right / consistent has
been a permanent source of mistakes. Reduce what needs specifying
manually to just the direct forward dependencies. Transitive forward
dependencies as well as reverse ones are now derived and hence cannot go
out of sync anymore (at least in the vast majority of cases; there are a
few special cases to still take care of manually). In the course of this
several CPU_ANY_*_FLAGS disappear, requiring adjustment to the
assembler's cpu_arch[].
Note that to retain the correct reverse dependency of AVX512F wrt
AVX512-VP2INTERSECT, the latter has the previously missing AVX512F
prereq added.
Note further that to avoid adding the following undue prereqs:
* ATHLON, K8, and AMDFAM10 gain CMOV and FXSR,
* IAMCU gains 387,
auxiliary table entries (including a colon-separated modifier) are
introduced in addition to the ones representing from converting the old
table.
To maintain forward-only dependencies between AVX (XOP) and SSE* (SSE4a)
(i.e. "nosse" not disabling AVX), reverse dependency tracking is
artifically suppressed.
As a side effect disabling of SSE or SSE2 will now also disable AES,
PCLMUL, and SHA (respective elements were missing from
CPU_ANY_SSE2_FLAGS).

gdb/c++: validate 'using' directives based on the current line
When asking GDB to print a variable from an imported namespace, we only
want to see variables imported in lines that the inferior has already
gone through, as is being tested last in gdb.cp/nsusing.exp. However
with the proposed change to gdb.cp/nsusing.exp, we get the following
failures:
(gdb) PASS: gdb.cp/nsusing.exp: continue to breakpoint: marker10 stop
print x
$9 = 911
(gdb) FAIL: gdb.cp/nsusing.exp: print x, before using statement
next
15 y += x;
(gdb) PASS: gdb.cp/nsusing.exp: using namespace M
print x
$10 = 911
(gdb) PASS: gdb.cp/nsusing.exp: print x, only using M
Showing that the feature wasn't functioning properly, it just so
happened that gcc ordered the namespaces in a convenient way.
This happens because GDB doesn't take into account the line where the
"using namespace" directive is written. So long as it shows up in the
current scope, we assume it is valid.
To fix this, add a new member to struct using_direct, that stores the
line where the directive was written, and a new function that informs if
the using directive is valid already.
Unfortunately, due to a GCC bug, the failure still shows up. Compilers
that set the declaration line of the using directive correctly (such as
Clang) do not show such a bug, so the test includes an XFAIL for gcc
code.
Finally, because the final test of gdb.cp/nsusing.exp has turned into
multiple that all would need XFAILs for older GCCs (<= 4.3), and that
GCC is very old, if it is detected, the test just exits early.

sim: sim_cpu: invert sim_cpu storage
Currently all ports have to declare sim_cpu themselves in their
sim-main.h and then embed the common sim_cpu_base in it. This
dynamic makes it impossible to share common object code among
multiple ports because the core data structure is always different.
Let's invert this relationship: common code declares sim_cpu, and
the port uses the new arch_data field for its per-cpu state.
This is the first in a series of changes: it adds a define to select
between the old & new layouts, then converts all the ports that don't
need custom state over to the new layout. This includes mn10300 that,
while it defines custom fields in its cpu struct, never uses them.

sim: dv-core: add hw_detach_address method [PR sim/25211]
The core device has an attach address method as the root of the tree
which calls out to the sim API. But it doesn't have a corresponding
detach method which means we just crash if anything tries to detach
itself from the core. In practice, the m68hc11 is the only model
that actually tries to detach itself on the fly, so no one noticed
earlier.
With this in place, we can delete the existing detach code from the
m68hc11 model since it defaults to "passthru" callback which will in
turn call the dv-core detach, and they have the same behavior -- call
the sim core API to detach from the address space.

Re: The problem with warning in elf_object_p
Commit
5aa0f10c424e added a per_xvec_warn array to provide support for
warnings from elf_object_p (and a later patch for warnings from
pe_bfd_object_p) to be cached and then only printed if the target
matches. It was quite limited in the style of message supported, only
one message could be printed, and didn't really meet the stated aim of
only warning when a target matches: There are many other errors and
warnings that can be emitted by functions called from elf_object_p.
So this patch extends the error handler functions to support printing
to a string buffer, extends per_xvec_warn to support multiple errors/
warnings, and hooks this all into bfd_check_format_matches. If
bfd_check_format_matches succeeds then any errors/warnings are printed
for the matching target. If bfd_check_format_matches fails either due
to no match or to multiple matches and only one target vector produced
errors, then those errors are printed.
