x86: Add YASM implementations of cpuid and xgetbv from x264

This allows detecting CPU features with builds that have neither
gcc inline assembly nor the right compiler intrinsics enabled.

Clean up av_get_cpu_flag()
...
Instead of defining functions in per-arch header files included
by the main cpu.c, define them normally and call them from the
generic one.

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>.

Convert asm keyword into __asm__.
...
Neither the asm() nor the __asm__() keyword is part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).
Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 syntax.
