In real-time mode, vp8_sad16x16 function is called heavily in
motion search part. Improvement of this function gives 1.2%
encoding performance gain (real-time mode, tulip clip).

x86-64 passes arguments in registers. There is no need to push
them to the stack before using them.
This fixes 15acc84f10 where ebx
was not getting preserved on x86.

nasm requires the instruction length (movd/movq) to match to its
parameters. I find it more clear to really use 64bit instructions when
we use 64bit registers in the assembly.
Provide nasm compatibility. No binary change by this patch with yasm on
{x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on
{x86_64,i686}-fedora13-linux-gnu have been checked as safe.

When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.
