Replace ASMALIGN with .p2align

This macro has unconditionally used .p2align for a long time and
serves no useful purpose.

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

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.

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

Move mm_support() from libavcodec to libavutil, make it a public
function and rename it to av_get_cpu_flags().

Rename FF_MM_ symbols related to CPU features flags as AV_CPU_FLAG_
symbols, and move them from libavcodec/avcodec.h to libavutil/cpu.h.

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...

Remove DECLARE_ALIGNED_{8,16} macros

These macros are redundant. All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

encoder.

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