> vp8_build_intra_predictors_mby{,_s}().
HD decode tests have shown a performance boost up to 1.5%,
depending on material.
Patch set 3: Fixed encoder crash.

ed9c66f584 Remove usage of predict buffer for decode
Instead of using the predict buffer, the decoder now writes
the predictor into the recon buffer.  For blocks with eob=0,
unnecessary idcts can be eliminated.  This gave a performance
boost of ~1.8% for the HD clips used.

Tero: Added needed changes to ARM side and scheduled some
      assembly code to prevent interlocks.

Patch Set 6:  Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3)
into this commit because of similarities in the idct
functions.
Patch Set 7: EC bug fix.

c5f890af2c Use local labels for jumps/loops in x86 assembly.
Prepend . to local labels in assembly code.  This
allows non unique labels within a file.  Also
makes profiling information more informative
by keeping the function name with the loop name.

c8a23ad3f4 Properly use GET_GOT/RESTORE_GOT when using GLOBAL().
This should fix binaries using PIC on x86-32. Also should
fix issue 343.

df2023a6cb set up Global Offset Table in recon
global values were being referenced, but the GOT was not being set up.
as the GOT is only required for PIC, this issue wasn't caught in the
default configuration.

1e7ded69cf Use psadbw to get the sum of bytes in a line.
Thanks Jason for pointing that out on #vp8. ;-).

4a2b684ef4 modify SAVE_XMM for potential 64bit use
the win64 abi requires saving and restoring xmm6:xmm15. currently
SAVE_XMM and RESTORE XMM only allow for saving xmm6:xmm7. allow
specifying the highest register used and if the stack is unaligned.

94c52e4da8 cosmetics: trim trailing whitespace
When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.

63ea8705eb some XMM registers are non-volatile on windows x64 ABI
XMM6 to XMM15 are non-volatile on Windows x64 ABI.  We have to save
these registers.
