filter it out in the compile line.

This checks which assembler syntax is supported and defines macros
for register names accordingly.

Also put compute_antialias_integer() under !CONFIG_FLOAT and change
forward declarations to declare only the relevant one of these.

Fixes warnings about unused functions and pointer type mismatches.

Originally committed as revision 23950 to svn://svn.ffmpeg.org/ffmpeg/trunk

The mmx code is floating-point only, and this function does not know
from which decoder it is called.  Without this change, the integer
decoder only "works" because the size of the context struct is smaller
in this case, and the mmx init function writes the function pointer
outside the allocated context.

Fixes issue 2054.

Originally committed as revision 23926 to svn://svn.ffmpeg.org/ffmpeg/trunk

Necessary because of this GCC bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44474
To do this, convert some, but not all (!) of the variables in VP56RangeCoder
into local variables.
If we convert c->high into a local variable, gcc gets the stupids and refuses
to use a conditional move for the unpredictable main branch.

TODO: dispense with this bullshit and write an asm version.

Originally committed as revision 23924 to svn://svn.ffmpeg.org/ffmpeg/trunk

This incantation causes gcc 4.3 to generate cmov on x86, a vastly better option
than a completely unpredictable branch.
Hopefully this carries over to newer versions and other CPUs with conditionals.
~5 cycles saved per call on a Core i7.

This function is called from the rv40_[hv]_loop_filter() wrappers
with some arguments constant, so it really needs to be inlined.
