  -----------
  [X86] Move all the FP_TO_XINT/XINT_TO_FP setOperationActions into the same !useSoftFloat block. Qualify all of the Promote actions for these with !useSoftFloat too. NFCI

The Promote action doesn't apply until LegalizeDAG. By the time
we get there, we would have already softened all the FP operations
if useSoftFloat was true. So there wouldn't be any operation left
to Promote.

  Log Message:
  -----------
  [X86] Don't set the operation action for i16 SINT_TO_FP to Promote just because SSE1 is enabled.

Instead do custom promotion in the handler so that we can still
allow i16 to be used with fp80. And f64 without sse2.
