initial merge of GCC 12.3.0.

this doesn't include any of the changes to the .c -> .cc files renamed,
and reverts our local changes to the vax port and libsanitizer subdir.
vax GCC was rewritten and our local fixes no longer are relevant, and
the new libsanitizer is more updated than our old one, and merging via
gcc10->gcc12 is not really possible.

unfortunately, our local changes to libsanitizer that aren't related
to the general update of those sources (ie, the netbsd code) will need
to be re-checked and perhaps re-ported.

merge GCC 10.5.0.

branches: 1.71.2;
merge GCC 10.4.0.

Fix GCC10 for arm.

Include order of bpapi.h and netbsd-elf.h was swapped when official
support for arm*--netbsdelf-eabi{,hf} was added to GCC10. This seems to
cause critical inconsistencies, which results in SIGSEGV for as(1) on
earmv6hf{,eb} and some other regressions for many arm variants.

With this fix, everything work just fine as far as I can see.

Thanks skrll and mrg for discussion!

Add support for mipsn64 targets which build 64 bit binaries by default
on instead of n32

arm/netbsd-elf.h is necessary for eabi targets.

reduce diffs to upstream slightly.

initial merge of GCC 10.3.0.

these three files are not yet finished merging:

gcc/config/rs6000/rs6000.c
libsanitizer/lsan/lsan_allocator.h
libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.h

our current GCC 9 sanitizers are newer than GCC 10's still, so that
may take a little to untease, so it's probable that more than
these 2 will need more changes.

rs6000.c has some changes related to ABI and supported functionality
that need to be merged forward.

don't include vxworks-dummy.h twice

merge GCC 9.3.0.

Teach config.gcc about NetBSD aarch64eb

merge GCC 8.4.0.

revert the powerpc config.gcc changes i made while merging,
they end up mis-ordering tm files.

revert the rs6000/netbsd64.h change and put it back as
SUBSUBTARGET_EXTRA_SPECS.


this seems to make the build work again, though mknative will
need a re-run for ppc*.

make sure to include bpabi.h before arm.h.

avoid multiple tm_file headers being listed and breaking builds.

- use /usr/include/gcc-8
- update sanitizer makefiles

also, reduce diffs to upstream:
- remove or1k support
- re-order various lines to match upstream
- move regex map code into file-prefix-map.[ch]

fix powerpc64 bi-arch support: provide a LINK_SECURE_PLT_SPEC.

for now, turn off biarch support in ppc64. it ends up enabling
secureplt support for 64 bit mode, which doesn't exist (or need it.)
