  Changed paths:
    M llvm/lib/Analysis/ConstantFolding.cpp
    M llvm/lib/Transforms/IPO/GlobalOpt.cpp
    A llvm/test/Transforms/GlobalOpt/x86_mmx_load.ll
    M llvm/test/Transforms/InstSimplify/ConstProp/loads.ll

  Log Message:
  -----------
  [ConstantFold][GlobalOpt] Don't create x86_mmx null value

This fixes the assertion failure reported at
https://reviews.llvm.org/D114889#3198921 with a straightforward
check, until the cleaner fix in D115924 can be reapplied.
