I just got a report of a fix for the FreeBSD
powerpc ABI's code generation in llvm. It should
fix a stack handling related problem that
currently makes clang (through 4) largely useless
for TARGET_ARCH=3Dpowerpc .

This would also apply to:

powerpc-unknown-freebsd12.0

not just 11.0

Hopefully it is an easy merge into
clang 4.
