dd025f25da Change AES code to be strict-aliasing-safe. 
Makes it give correct results with e.g. gcc 4.4.
For unknown reasons the generate asm code also changes
on e.g. gcc 4.3, making the code a bit larger but also
a bit faster.

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.

3% faster overall on Cortex-A8.

7ed06b2be8 Simplify MV parsing, removes laying out 2 or 4 (16x8/8x8/8x16) MVs over all 
16 subblocks (since we no longer need that), which should also lead to a
minor speedup.

7c4dcf8165 Optimize split MC, so we don't always do 4x4 blocks of 4x4pixels each, but 
we apply them as 16x8/8x16/8x8 subblocks where possible. Since this allows
us to use width=8/16 instead of width=4 MC functions, we can now take more
advantage of SSE2/SSSE3 optimizations, leading to a total speedup for splitMV
filter of about 10%.
