x64 always has MMX, MMXEXT, SSE and SSE2 and this means
that some functions for MMX, MMXEXT, SSE and 3dnow are always
overridden by other functions (unless one e.g. explicitly
disables SSE2). This commit therefore disables
the MMX and 3dnow implementations (overridden by MMXEXT)
and a single MMXEXT function (overridden by SSE2)
at compile-time for x64.
