Pull in r241142 from upstream llvm trunk (by David Majnemer):

  [SCCP] Turn loads of null into undef instead of zero initialized values

  Surprisingly, this is a correctness issue: the mmx type exists for
  calling convention purposes, LLVM doesn't have a zero representation for
  them.

  This partially fixes PR23999.

Pull in r241143 from upstream llvm trunk (by David Majnemer):

  [LoopUnroll] Use undef for phis with no value live

  We would create a phi node with a zero initialized operand instead of
  undef in the case where no value was originally available.  This was
  problematic for x86_mmx which has no null value.

These fix a "Cannot create a null constant of that type!" error when
compiling the graphics/sdl2_gfx port with MMX enabled.
