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.

x86/doc/Makefile: DBG=1 to preprocess external asm
...
The macro hell sometimes make it difficult to trace the source of
an error, so it is easier to analyze the preprocessed output.
This patch makes this automatical by specifying DBG=1 on the
command line: a file ffmpeg/dir/file.asm gets preprocessed to
builddir/dir/file.dbg.asm, which is then compiled.

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.

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.
