  Changed paths:

    M llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp
    M llvm/lib/Target/AArch64/AArch64TargetMachine.cpp

  Log Message:
  -----------
  Reland [AArch64][NFC] Call the API getVScaleRange directly

Use the maximum 64 for BitWidth of getVScaleRange to avoid returning an empty range.

the previous changes bring in a Buildbot failure because MinSVEVectorSize = MinSVEVectorSize.
    error: explicitly assigning value of variable of type 'unsigned int' to itself [-Werror,-Wself-assign]
