8bbdd20a29 aacenc: Fix erasure of surround channels 
This was due to a miscomputation of s->cur_channel, which led to
psy-based encoders using the psy coefficients for the wrong channel.

f4d0a63b5b aacenc: Fix target bitrate for twoloop quantiser search 
This fixes a case where multichannel bitrate isn't accurately
targetted by psy model alone, never achieving the target bitrate.

f54b55058a configure: Rename cmov processor capability to i686 
The goal is to make the capapility slightly more general and have it
cover the availability of the nopl instruction in addition to cmov.

94235f2ba2 indeo3: avoid writes without necessary alignment in copy_cell() 
Cells starting at a position aligned to 8 pixels but wider than
4 blocks are copied with 3 blocks per loop. This creates problems on the
next loop iterations since the routine copying 2 blocks requires the
same alignment on some architectures like ARM NEON.

4a7af92cc8 sbrdsp: Unroll and use integer operations 
This patch can be controversial, by assuming floats are IEEE-754 and
particular behaviour of the FPU will get in the way.
Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference).

sbr_qmf_pre_shuffle_c: 115 to 76
sbr_neg_odd_64_c: 84 to 55
sbr_qmf_post_shuffle_c: 112 to 83

Unrolling is another 7 cycle gain.
Working in reverse scan is another 6 cycles.
