[FFmpeg-devel] [PATCH 23/41] avcodec/x86/sbrdsp_init: Disable overridden functions on x64

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

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). This commit therefore disables
ff_sbr_qmf_deint_bfly_sse (which is overridden by an SSE2 function)
at compile-time for x64.
