various updates to build native GCC 12.

- for usr.bin, build libcody and link it into cc1*plus
- move makefile code for auto-build.h and version.h (was gcov-iov.h)
into makefile fragment to share them. (XXX probably best to only do
this in one place, but that's a future step.)
- many updates to handle the .c -> .cc renames
- build some x86 files with -msse2
- bump shlib versions for libgomp and libstdc++v3
- fix MKGCCCMDS=no builds
- updates for new rtl-ssa subdir
- use -std=gnu++11 for various places
- define TARGET_MACHINE and HOST_MACHINE for some places
- avoid a .BEGIN rule that writes to missing obj (ie src) sometimes

cleanups still needed:
- remove a bunch of commented -Wno* that don't seem to be needed anymore
- leave or remove various vax-specific -O0s that should no longer be
necessary for the vax-gcc port
- some "XXXGCC12" that should be may be fixable or converted to using our
standard ${CC_...} warnings (but may need to remain, in which case the
XXXGCC12 marker will be removed.)

with these, and a few other changes around the tree, i've able to build
gcc12 releases for several ports that seem to work (arm64, sparc, amd64,
i386 at least so far, have run, several others have built.)

Revert the change for the c-common.c hack. It is meant to be only for 32
bit mips. (Thanks Rin)

various changes to get GCC 10 to build here.

- fix path to compiler-specific includes
- missing (void) for (older) C
- fix __is_signed/__is_signed_val change
- avoid compiler warning-as-errors
- add to existing COPTS.file values, instead of setting
- bump libgomp minor; functions were added
- add new 'compare' c++ header
- handle new analyzer subdirectory. set TARGET_MACHINE for lto-streamer-in.c.
remove params.list etc handling.
- coroutines.cc is another .cc not .c. adjust .PATH to suit.
- add new lto1 sources
- couple of files not in /arch/ subdirs missed in mknative update.

rs6000.c is still not merged.

make GCC 9.3.0 build itself:
- common-target is needed before common now
- complete build-sort.o framework
- fix cyclic dep
- fix .c vs .cc issues

Fix addition of C++ .cc source to SRCS

Fix assumption that all of the source files are .c, as some are .cc.

installed into eg, /usr/lib/gcc. not convinced it is worth it.
