08e3ea60ff x86: synth filter float: implement SSE2 version 
Timings for Arrandale:
          C    SSE
win32:  2108   334
win64:  1152   322

Factorizing the inner loop with a call/jmp is a >15 cycles cost, even with
the jmp destination being aligned.

Unrolling for ARCH_X86_64 is a 20 cycles gain.

0cffd6fff5 x86: use the inline int8x8_fmul_int32 only if inline SSE2 is availbale 
Fixes compilation with MSVC. Also does not rely on on earlier config.h
include but include it directly.

5b59a9fc61 x86: dcadsp: implement int8x8_fmul_int32 
For the callable function (as opposed to the inline one):
         C  SSE  SSE2  SSE4
Win32:  47   42   29    26
Win64:  30   33   25    23
The SSE version is neither compiled nor set for ARCH_X86_64, as the
inlinable function takes over.

51daafb02e x86: videodsp: Properly mark sse2 instructions in emulated_edge_mc as such. 
Should fix crashes or corrupt output on pre-SSE2 CPUs when they were
using SSE2-code (e.g. AMD Athlon XP 2400+ or Intel Pentium III) in
hfix or hvar single-edge (left/right) extension functions.

3d7c84747d x86: Initialize mmxext after amd3dnow optimizations

amd3dnow optimizations are being deprecated. Thus the former should

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XvMC has long ago been superseded by newer acceleration APIs, such as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.

pointer as often, reducing the number of instructions as
well as code size.
