This change adds the configury bits to activate the build of
shared libs on VxWorks ports configured with --enable-shared,
for libraries variants where this is generally supported (rtp,
code model !large - currently not compatible with -fPIC).
Set lt_cv_deplibs_check_method in libtool.m4, so the build of
libraries know how to establish dependencies. This is useful in
configurations such as aarch64 where proper support of LSE relies
on accurate dependency information between libstdc++ and libgcc_s
to begin with.
Regenerate configure scripts to reflect libtool.m4 change.

* libtool.m4 (*vxworks*): When enable_shared, set dynamic_linker
and friends for rtp !large. Assume the linker has the required
abilities and set lt_cv_deplibs_check_method.
gcc/
* config.gcc (*vxworks*): Add t-slibgcc fragment
if enable_shared.
libgcc/
* config.host (*vxworks*): When enable_shared, add
libgcc and crtstuff "shared" fragments for rtp except
large code model.
(aarch64*-wrs-vxworks7*): Remove t-slibgcc-libgcc from
the list of fragments.

The latest libsanitizer import broke Solaris 11.3 bootstrap again, due
to an oversight of mine. A fix has been committed upstream
https://reviews.llvm.org/D133556
This patch cherry-picks it. Tested on Solaris 11.3 and 11.4, SPARC and
x86.

llvm-project revision 1cd4d63fb9ab0f04c7151911dde0d58b673823de.
The latest merge to libsanitizer includes changes to handle macOS 13+.
However, these changes are incompatible with GCC and so we need to find
an alternate solution. To restore bootstrap back this change out until
the alternate can be found.
The LoongArch support for libubsan and libasan has been added in:
- https://reviews.llvm.org/D129371
- https://reviews.llvm.org/D129418
and we've merged them in r13-2269. It's time to enable them.
No unexpected failures in GCC asan.exp and ubsan.exp tests.

Signed-off-by: Dimitrije Milosevic <dimitrije.milosevic@syrmia.com>.
The libsanitizer build has been broken on Solaris 11.3 by the latest
import. An upstream patch to fix this has now been committed:
[sanitizer_common] Support Solaris < 11.4 in GetStaticTlsBoundary
https://reviews.llvm.org/D120059
I'd like to cherry-pick it into libsanitizer, too.
Bootstrapped without regressions on sparc-sun-solaris2.11,
i386-pc-solaris2.11 (both Solaris 11.3 and 11.4), and
x86_64-pc-linux-gnu.

Bootstrapped and regtested on mips64-linux-gnuabi64.
bootstrap-ubsan revealed 3 bugs (PR 104842, 104843, 104851).
bootstrap-asan did not reveal any new bug.

-fsanitize=address imply -fasynchronous-unwind-tables. This is
needed by libasan for stack backtrace on MIPS.
(mips_asan_shadow_offset): Return SUBTARGET_SHADOW_OFFSET.
gcc/testsuite:
* c-c++-common/asan/global-overflow-1.c: Skip for MIPS with some
optimization levels because inaccurate debug info is causing
dg-output mismatch on line numbers.
* g++.dg/asan/large-func-test-1.C: Likewise.
libsanitizer/

I've cherry-picked following fix from llvm-project. Recent glibcs
have _thread_db_sizeof_pthread symbol variable which contains the
size of struct pthread, so that sanitizers don't need to guess that
and risk that it will change again.
