[VectorLegalizer] Enable TargetLowering::expandFP_TO_UINT support.

Add vector support to TargetLowering::expandFP_TO_UINT.

This exposes an issue in X86TargetLowering::LowerVSELECT which was assuming that the select mask was the same width as the LHS/RHS ops - as long as the result is a sign splat we can easily sext/trunk this.
