[PowerPC ABI] Bug 21398 - Consider C++ base classes in homogeneous aggregate classification

[Ulrich Weigand]

Hello,

as discussed in Bug 21398, PowerPC ABI code currently ignores C++ base
classes when classifying a class as homogeneous aggregate (or not) for ABI
purposes.  The attached patch fixes this.

Tested on powerpc64le-linux.  Also ran GCC's ABI compatibility test suite
against clang with no new failures (unfortunately, it didn't catch the
bug).

OK for mainline?

Mit freundlichen Gruessen / Best Regards
