Summary

Pull in r221170 from upstream clang trunk (by Roman Divacky):

Implement vaarg lowering for ppc32. Lowering of scalars and
aggregates is supported. Complex numbers are not.

Test Plan

Since I have no way of knowing whether this works correctly or not, I would like both a sanity check, and a check that this results in working va_args support on real PowerPC hardware.

I did build it, both with clang and gcc (I had to remove one C++11-ism), and it should compile OK.
