(ix86_expand_floorceildf_32): Same for DFmode on 32bit archs.
* config/i386/i386.md (floordf2): Adjust to enable floor
expansion via ix86_expand_floorceil if TARGET_SSE_MATH and
-fno-trapping-math is enabled and if not optimizing for size.
(floorsf2, ceildf2, ceilsf2): Likewise.
* config/i386/sse.md (sse_maskcmpsf3): New insn.
(sse2_maskcmpdf3): Likewise.
