Pull in r280188 from upstream llvm trunk (by Hal Finkel):

  [PowerPC] Don't spill the frame pointer twice

  When a function contains something, such as inline asm, which
  explicitly clobbers the register used as the frame pointer, don't
  spill it twice. If we need a frame pointer, it will be saved/restored
  in the prologue/epilogue code.  Explicitly spilling it again will
  reuse the same spill slot used by the prologue/epilogue code, thus
  clobbering the saved value. The same applies to the base-pointer or
  PIC-base register.

  Partially fixes PR26856. Thanks to Ulrich for his analysis and the
  small inline-asm reproducer.
