copy cabac context onto the stack for the c code in decode_cabac_residual() (15% faster on P3 but still slower then the current asm)

x86 asm version of the decode significance loop (not 8x8) of decode_residual() 5% faster decode_residual() on P3

fix !CMOV_IS_FAST case (iam not really happy with the fix but i didnt come up with a better one quickly)

shift CABACContext.range right, this reduces the number of shifts needed in get_cabac() and is slightly faster on P3 (and should be much faster on P4 as the P4 except the more recent variants lacks an integer shifter and so  shifts have ~10 times longer latency then simple operations like adds)
