Loren MerrittandDerek Buitenhuis e52567c295 build: Strip spurious labels 
The implementation of 25cb0c1a involves lots of spurious labels.

The effect of keeping those labels around is making debugging harder.
Those labels are meaningless, and complicate the disassembly. Also,
gdb can't tell the difference between them and function entry points.

This new strip command is irrelevant to any usage of Libav that would
have used the old fully stripped version, because the old one was for
non-debug use.

Loren MerrittandLuca Barbato c93ccf5a4c lpc: use levinson for the first pass of multipass cholesky 
Levinson is faster, and cholesky is only needed if we want to apply different
weights to different samples, which doesn't happen on the first pass.

Loren MerrittandRonald S. Bultje 2f7f2e4b41 Update x86inc.asm to latest x264 version, and add AVX symmetry. 
We keep INIT_AVX (for backwards compatibility). 3arg AVX ops with
a memory arg can only have it in src2, whereas SSE emulation of
3arg prefers to have it in src1 (i.e. the mov). So, if the op is
symmetric and the wrong one is memory, swap them.

Loren Merritt 5eb0f2a425 float_to_int16_interleave: change src to an array of pointers instead of assuming it's contiguous.

Loren MerrittandMike Melanson 96275520a3 Fix H.264 interframe decoding when compiling with icc. Patch by Loren 
Merritt:

"It seems that icc copies the constants from their global var onto the
stack, at which point they're not aligned, hence the crash.
[This change] really shouldn't mean anything different, but maybe it'll
confuse icc into not performing that 'optimization'."
