  Log Message:
  -----------
  [AArch64] Avoid SCALAR_TO_VECTOR for single FP constant vector.

Currently the code only checks for integer constants (ConstantSDNode)
and triggers an infinite cycle for single-element floating point
vector constants. We need to check for both FP and integer constants.
