6c3d021891 Properly add HAVE_YASM around yasmified symbols. Should fix compile error 
on configurations using --disable-yasm.

e2e341048e Move hadamard_diff{,16}_{mmx,mmx2,sse2,ssse3}() from inline asm to yasm, 
which will hopefully solve the Win64/FATE failures caused by these functions.

d0acc2d2e9 Move sse16_sse2() from inline asm to yasm. It is one of the functions causing 
Win64/FATE issues.

6526976f0c Remove FF_MM_SSE2/3 flags for CPUs where this is generally not faster than 
regular MMX code. Examples of this are the Core1 CPU. Instead, set a new flag,
FF_MM_SSE2/3SLOW, which can be checked for particular SSE2/3 functions that
have been checked specifically on such CPUs and are actually faster than
their MMX counterparts.

In addition, use this flag to enable particular VP8 and LPC SSE2 functions
that are faster than their MMX counterparts.

Based on a patch by Loren Merritt <lorenm AT u washington edu>.

84dc2d8afa Remove DECLARE_ALIGNED_{8,16} macros 
These macros are redundant.  All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

a6493a8fbd Rename libavcodec/i386/ --> libavcodec/x86/. 
It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.
