Andreas Rheinhardt dd61d6489b swresample/x86/resample: Remove obsolete MMXEXT functions
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). So given that the only systems which benefit
from the MMXEXT resamplers (which are overridden by SSE2)
are truely ancient 32bit x86s they are removed.
