  Log Message:
  -----------
  [SelectionDAG][X86] Mutate strictFP nodes to non-strict in DoInstructionSelection when the node is marked Expand rather than when it is not Legal.

This allows operations that are marked Custom, but have some type
combinations that are legal to get past this code.

Add custom mutation code to X86's Select function for the nodes
that don't have isel patterns yet.
