build: Prefer NASM assembler over YASM
...
NASM is more actively maintained and permits generating dependency information
as a sideeffect of assembling, thus cutting build times in half.

It does not help as an abstraction and adds dsputil dependencies.

Update docs regarding writing optimizations:
...
- mention clobber-marking of xmm registers,
- some notes on external vs. inline asm, including tips on which to use for
what situation and to not rewrite+improve in the same patch (as with C code)
- some more best-practice guidelines
See "[PATCH] update doc/optimization.txt" thread on ML.

Rename libavcodec/i386/ --> libavcodec/x86/.

It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.

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.
