  Changed paths:
    M llvm/lib/Target/SystemZ/SystemZTargetTransformInfo.cpp
    A llvm/test/Analysis/CostModel/SystemZ/huge-immediates.ll

  Log Message:
  -----------
  [SystemZ] Make sure not to call getZExtValue on a >64 bit constant.

Better use isZero() and isIntN() in SystemZTargetTransformInfo rather than
calling getZExtValue() since the immediate operand may be wider than 64 bits,
which is not allowed with getZExtValue().
