The insertps's of $0 are pointless complex copies.
//===---------------------------------------------------------------------===//
If SSE4.1 is available we should inline rounding functions instead of emitting
a libcall.
floor: roundsd $0x01, %xmm, %xmm
ceil: roundsd $0x02, %xmm, %xmm
and likewise for the single precision versions.
Currently, SelectionDAGBuilder doesn't turn calls to these functions into the
corresponding nodes and some targets (including X86) aren't ready for them.
