Dimitry Andric 5f4899dbfe 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.
