clang needs HAVE_MMX to be first in order to avoid an undefined
reference error.

Using rNm and x86inc's stack allocation with a negative value at the same
time isn't supported, and caused the original stack pointer to be clobbered
when using a compiler that doesn't support stack alignment.

This can provide a manual workaround for ticket #4230.

The parser only parses the core, and thus has a duration relative
to the core sample rate only, not the actual stream sample rate.

FATE references changed due to now correct timestamps.
