[PATCH, i386]: Committed: Use ix86_expand_convert_uns_sisf_sse also for TARGET_SSE.

[Uros Bizjak]

Hello!

There is simply no reason not to use specialized SSE unsigned SI -> SF 
expander also for TARGET_SSE, since ix86_expand_convert_uns_sisf_sse 
expands to SSE-only instructions. This change also enables macroization 
(iteratization?) of similar patterns.

Patch was bootstrapped and regression tested on x86_64 {,-m32}, applied 
to SVN as obvious.

        * config/i386/i386.md (floatunsisf2): Use
        ix86_expand_convert_uns_sisf_sse also for TARGET_SSE.
        (floatunsi<mode>2): Rename from floatunsisf2 and
        floatunsidf2.  Macroize expander using MODEF mode iterator.

Uros.
