3d7c84747d x86: Initialize mmxext after amd3dnow optimizations 
The mmxext optimizations should be at least equally fast if available and
amd3dnow optimizations are being deprecated. Thus the former should
override the latter, not the other way around.

458446acfa lavc: Edge emulation with dst/src linesize 
Allow supporting files for which the image stride is smaller than
the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9
file or a 16x16 VP8 file with -fflags +emu_edge.

19e30a58fc Deprecate obsolete XvMC hardware decoding support 
XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.

bbe4a6db44 x86inc: Utilize the shadow space on 64-bit Windows 
Store XMM6 and XMM7 in the shadow space in functions that
clobbers them. This way we don't have to adjust the stack
pointer as often, reducing the number of instructions as
well as code size.

Most of our VP56 optimizations are VP6-only and will stay that way.
