b223035511 Detect and check for CMOV.
Some MMX-only CPUs do not have support for CMOV.
All SSE/MMX2 CPUs should be fine, thus no check was
added to those functions.

19a0729b4c Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder.
This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

Preparatory patch for high bit depth h264 decoding support.

98928c83e0 Mark recently added pred4x4_down_left_mmxext as CONFIG_GPL. Although Holger
initially said he'd be OK with relicensing, he also said he wanted to have
another look at the patch, and then he went on vacation, so let's play it
safe for now. We can consider removing this again later.

dd68d4db43 MMX, MMX2, SSE2 and SSSE3 optimizations for pred16x16/8x8_plane H264 intra
prediction (plus some with different rounding for svq3/rv40). Speedup (for
SSSE3) about ~6-fold, 3.6% faster overall with cathedral sample.
