Log:
Headers: conditionalise more declarations
Protect MMX specific declarations under a __MMX__ guard. This header can be
included on non-x86 architectures (e.g. ARM) which do not support the MMX ISA.
Use the preprocessor to prevent these declarations from being processed.

The commit message was great, but the test itself could do with a
one-liner comment explaining what's being tested.
