The new fdct lowers the round trip sum squared error for a
4x4 block ~0.12. or ~0.008/pixel. For reference, the old
matrix multiply version has average round trip error 1.46
for a 4x4 block.
Thanks to "derf" for his suggestions and references.

Added sse2 version of vp8_regular_quantize_b which improved encode

64 bit builds.
Also updated SHADOW_ARGS_TO_STACK to allow for more than 9 arguments.
