[PATCH, rs6000] Tests of ARCH_PWR8 and -mno-vsx option.

Hi,

This adds an assortment of tests to exercise the -mno-vsx option and
confirm the impacts on the ARCH_PWR8 define.

These are based on and inspired by PR 101865, which
reports that _ARCH_PWR8 is disabled when -mno-vsx
is passed on the commandline.

There are a small number of failures introduced by these tests,
those are resolved with the changes in part 2.

OK for trunk?
Thanks,
-Will
