  Changed paths:
    M llvm/lib/Target/AArch64/AArch64TargetTransformInfo.cpp
    A llvm/test/Transforms/SLPVectorizer/AArch64/shuffle-vectors-mask-size.ll

  Log Message:
  -----------
  [COST][AARCH64]Fix crash in cost calculation for shuffles.

Need to take the mask size as number of elements, not the number of
elements of the original fixed vector. Otherwise, the compiler may
crash.
