Subject: [PATCH] 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.
