166f399377 x86inc: support yasm -f win64 flag also.
This sets __OUTPUT_FORMAT__ to win64 instead of win32, even though both
(through -m amd64) produce 64-bit binary code.

9cf7385309 x86inc: allow manual use of WIN64_SPILL_XMM.
Functions using INIT_MMX may still access XMM registers through direct
means (xmm0-15). Therefore, they still need to be marked for clobber
so they can be properly saved/restored.

7e4d9d5d45 win64: add a XMM clobber test configure option.
This will be useful to test more aggressively for failures to mark XMM
registers as clobbered in Win64 builds, and prevent regressions thereof.

5b0d35eaed x86: bswap: remove test for bswap instruction
Firstly, this test never worked as intended, always reporting
success.  Secondly, bswap is available from 486 onward and can
thus be assumed present.

f64c2e710f bswap: make generic implementation more compiler-friendly
With these changes, gcc 4.5 and later recognise it as a bswap
and use the proper instructions on ARM and x86.  On x86, the
16-bit bswap is recognised from gcc 4.1.

be0675ce67 x86 cpuid: set vendor union members separately
Solaris Studio (suncc) has difficulty with filling in
members of a union. Instead, let's retrieve and store the
cpuid() results separately. This is still a compiler bug,
however this fix does not cause a regression on other platforms.

6b6ee58249 x86inc: Flag shufps as an floating-point instruction for the AVX emulation code.
Without this, code like "shufps m0, m1, m2, 0xaa" would not work in CPUs
not supporting SSE2.

2f7f2e4b41 Update x86inc.asm to latest x264 version, and add AVX symmetry.
We keep INIT_AVX (for backwards compatibility). 3arg AVX ops with
a memory arg can only have it in src2, whereas SSE emulation of
3arg prefers to have it in src1 (i.e. the mov). So, if the op is
symmetric and the wrong one is memory, swap them.

15919ee48f bswap: use native types for av_bwap16().
This prevents a call to bytestream_get_be16() using a movzwl both before
and after the ror instruction, which is obviously inefficient. Arm uses
the same trick also.

Sintel decoding goes from (avg+SD) 9.856 +/- 0.003 to 9.797 +/- 0.003 sec.

eba586b0d9 Add a CPU flag for the Atom processor.
The Atom has SSSE3 support, which is useful in many cases, but sometimes the
SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally
faster on other processors supporting SSSE3. This flag allows for selectively
disabling certain SSSE3 functions on the Atom.
