835954e3a4 support seperating expressons by ; 
support variables, the syntax isnt beautifull (st(a,b) means var[a]=b and ld(a) var[a]) but for a mere 19 lines of code its fairly simple, if anyone wants to write real variables support with names for variables and = and [] then that would of course be welcome but only if it doesnt bloat the code up terribly...)

ebd624b662 optimize sign decoding code in decode_residual() 
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

f24a515931 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)
