  -----------
  [LegalizeTypes] Remove the call to SplitVecRes_UnaryOp from SplitVecRes_StrictFPOp. NFCI

It doesn't seem to do anything that SplitVecRes_StrictFPOp can't
do. SplitVecRes_StrictFPOp already handles nodes with a variable
number of arguments and a mix of scalar and vector arguments.

  Log Message:
  -----------
  [LegalizeTypes] Remove ScalarizeVecRes_STRICT_FP_ROUND in favor of just using ScalarizeVecRes_StrictFPOp. NFCI

It looks like ScalarizeVecRes_StrictFPOp can handle a variable
number of arguments with scalar and vector types so it should
be sufficient.

  Log Message:
  -----------
  [LegalizeTypes] Pre-size the SmallVectors in ScalarizeVecRes_StrictFPOp and SplitVecRes_StrictFPOp so we don't have to call push_back. NFCI

This avoids grow checking/handling in each iteration of the loop.
