PATCH: New 32 bit wcscmp implementation

[Dmitrieva Liubov]

Hello,

I've optimized wcscmp function (new implementation is written with
assembly language coding), it looks better than current version for
all machines with SSE2 supporting I have.

It improves performance by up to 3X.

This patch should be applied after 64bit wcscmp patch since shared
change in wcsmbs/wcscmp.c is required for this patch as well.
