Andreas Rheinhardt f76477d4d7 avcodec/x86/vorbisdsp: Remove obsolete 3dnow 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 3dnow implementations are truely ancient 32bit AMD x86s
they are removed.
