[UpdateTestChecks] [PowerPC] Add powerpc- triple support

[jsji]

Summary

There are quite some old testcases with powerpc- triple,
we should add this triple support so that we can update them with script.

Appears identical to powerpc64{,le}, ppc32.
Regenerate one test that is being affected by upcoming patch.

Haven't seen assembly generated for AIX 32 (powerpc-ibm-aix-xcoff),
but we should be able to use the same one as well,
or else, we can fix it later when AIX 32 asm support lands.

These are identical to that new 'powerpc' entry, and given that the matching is 'lossy', they can be dropped.

Good point! Updated to remove powerpc64 and powerpc64le.

Looks good.
