Log:
  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.
