[PowerPC] Support powerpcle target in Clang [3/5]

[Bdragon28]

Summary

Add powerpcle support to clang.

For FreeBSD, assume a freestanding environment for now, as we only need it in the first place to build loader, which runs in the OpenFirmware environment instead of the FreeBSD environment.

For Linux, recognize glibc and musl environments to match current usage in Void Linux PPC.

Adjust driver to match current binutils behavior regarding machine naming.

Adjust and expand tests.

This needs a linker test in clang/test/Driver/ppc-features.cpp

Please format

"-unknown" is correct, though I usually omit it as it is not useful...

[Bdragon28]

• Adjust the GNU LD settings for 32 bit powerpc to more closely match reality.
• Add linker emulation test for powerpcle, as well as adding testing for the FreeBSD emulations.

This is actually intentional!

I needed to force it to emit the hyphen so I could tell powerpc apart from powerpcle. The same for powerpc64, the BE test was actually not working properly as is because it would also match on LE.

You can write "-triple" "powerpcle" ..

I think the driver side works even without TargetInfo change

Update altivec changes after fd739804e0591468762eb87488a497a3f7d4afb0.
