LOG: [LegalizeTypes] Remove incomplete StrictFP support from SplitVecRes_UnaryOp. NFC

There is no handling of Chain operands in this function so it can't
work. There's a separate splitting function for all strict fp nodes.

Added:

    llvm/lib/CodeGen/SelectionDAG/LegalizeVectorTypes.cpp

Removed:
