x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from ff_sbr_qmf_deint_bfly_sse are truely ancient 32bit x86s it is removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
