make this actually be GCC 12.3.0's libsanitizer.

the libsanitizer we used with GCC 9 and GCC 10 was significantly
ahead of the GCC 9 and GCC 10 provided versions.

revert sanitizer back to the version we were using with GCC 9, since
that one was already newer than the GCC 10 version.

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.

import GCC 6.4.0.  see this url for details which are too large to
include here:

   http://gcc.gnu.org/gcc-6/changes.html

the main visible changes appear to be:

- The default mode for C++ is now -std=gnu++14 instead of -std=gnu++98.
- The C and C++ compilers now support attributes on enumerators.
- Diagnostics can now contain "fix-it hints"
- more warnings (some added to -Wall)
