MFC r317810:
Pull in r302183 from upstream llvm trunk (by Krzysztof Parzyszek):
[PPC] When restoring R30 (PIC base pointer), mark it as <def>
This happened on the PPC32/SVR4 path and was discovered when building
FreeBSD on PPC32. It was a typo-class error in the frame lowering
code.
This fixes PR26519.
