That was for a Core1, now here's one for x86-64:

C:
real	1m47.649s
user	1m47.411s
sys	0m0.218s

SIMD:
real	0m52.142s
user	0m51.943s
sys	0m0.187s

libvpx:
real	0m50.346s
user	0m50.041s
sys	0m0.295s

Jason has suggested a variety of ways to take more advantage of
SSSE3/SSE4 instructions (which I basically didn't really focus on
because my CPU doesn't support it), and more generally to be a little
more efficient with registers in non-looping functions (e.g. all
loopfilter functions in >=SSE2), which should allow us to speed it up
quite a bit more. David also showed some progress on block coeff
optimizations, so we'll probably be able to shave off a few seconds
more.
