2cbd734a38 Maybe fix threaded mpeg*video encoding 
This allocates per-thread copies of some MpegEncContext.ac_val which
is used concurrently from the encoding threads.

4148855ee4 Eliminate another redundant instruction in vp56/8 arithcoder 
Necessary because of this GCC bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44474
To do this, convert some, but not all (!) of the variables in VP56RangeCoder
into local variables.
If we convert c->high into a local variable, gcc gets the stupids and refuses
to use a conditional move for the unpredictable main branch.

TODO: dispense with this bullshit and write an asm version.

36d6b545a1 CMOV-ify vp56 arithcoder 
This incantation causes gcc 4.3 to generate cmov on x86, a vastly better option
than a completely unpredictable branch.
Hopefully this carries over to newer versions and other CPUs with conditionals.
~5 cycles saved per call on a Core i7.

dd8e127a4d rv40: make rv40_adaptive_loop_filter() always_inline 
This function is called from the rv40_[hv]_loop_filter() wrappers
with some arguments constant, so it really needs to be inlined.
