Subject: Remove detection for MMX support and related technology

This also removes the check for SSE, but the check for SSE2 and
further technologies is kept. If SSE2 is present, then SSE is too. We
don't have any code that uses the original SSE instructions only.

Remove the CMOV detection, since we don't use that anywhere and we're
not likely to ever use them..
