  Changed paths:
    M llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp
    A llvm/test/Transforms/SLPVectorizer/X86/mask-size-less-common-mask.ll

  Log Message:
  -----------
  [SLP]Match the mask size, when copying mask for full match

Need to be careful, when filling the mask for fully matched nodes, the
masks may differ in sizes

Fixes a crash reported in test/Transforms/SLPVectorizer/X86/mask-size-less-common-mask.ll
