1 variable less in decode_cabac_residual() no speed change (but less vars means less things gcc can load and store redundantly)

x86 is 4% faster on P3
C sign stuff + x86 code for everything else is also faster then before (sorry forgot to test pure C)
... and if i replace the second occurance of the sign decoding in decode_residual by the asm too then everything gets slower iam starting to think that it might be best to write the whole function in asm, playing this avoid random deoptimizations game with gcc is not fun at all

Note that previous implementation (--tune) wasn't consistent with regards to setting -march/-mcpu/-mtune whereas current --cpu now is

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

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)
