  Changed paths:
    M llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp

  Log Message:
  -----------
  [LegalizeVectorOps] Expand vector MERGE_VALUES immediately.

Custom legalization can produce MERGE_VALUES to return multiple
results. We can expand them immediately instead of leaving them
around for DAG combine to clean up.

  [LegalizeVectorOps] Parallelize the lo/hi part of STRICT_UINT_TO_FLOAT legalization.

The lo and hi computation are independent. Give them the same input
chain and TokenFactor the results together.
