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

This includes SSE2 luma deblocking code and both MMXEXT and SSE2 luma
intra deblocking code for H.264 decoding. This assembly is available
under --enable-gpl and speeds decoding of Cathedral by 7%.

There are multiple source files that are #include'd rather than
compiled, as they are used as template for generation of similar code,
like asm-optimised code. Some of these files are right now named with
a .h extension, although they are not header in any reasonable sense.
Rename them so that instead of being named with .h extension they are
named with _template.c as final part.

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.
