Subject: [PATCH] Fix the SSE related AMD64 build breakage

The introduction of pixman_have_sse() copied the #ifdef __amd64__
found around pixman_have_mmx() in pixman-mmx.c but didn't include the
equivalents of the macros in pixman-mmx.h. As a result, the AMD64 link
fails because the pixman_have_sse() function doesn't exist.

I also introduced header inclusion guards to pixman-mmx.h and
pixman-sse.h while I was at it.

SSE support doesn't exist yet and it's already broken on AMD64. *sigh*
