  Changed paths:
    M llvm/lib/Target/X86/X86ISelLowering.cpp

  Log Message:
  -----------
  [X86] isRepeatedTargetShuffleMask - don't require specific MVT type. NFC.

Split the isRepeatedTargetShuffleMask into a wrapper variant that takes a MVT describing the mask width, and an internal version that just needs the raw mask element bit size.

This will be necessary for an upcoming change where the horizontal ops element width might not match the shuffle mask element width.
