0f7e4665ae Make libvpx Chromium build friendly
Add PRIVATE macro for adding private_extern directive for yasm
to hide global symbols. This is only enabled if -DCHROMIUM is used
with YASM.

Also fixed a small problem with	rtcd_defs.sh to guard TEMPORAL_DENOISING.

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

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.

c7cfde42a9 Add save/restore xmm registers in x86 assembly code
Went through the code and fixed it. Verified on Windows.

Where possible, remove dependencies on xmm[67]

Current code relies on pushing rbp to the stack to get 16 byte
alignment. This broke when rbp wasn't pushed
(vp8/encoder/x86/sad_sse3.asm). Work around this by using unaligned
memory accesses. Revisit this and the offsets in
vp8/encoder/x86/sad_sse3.asm in another change to SAVE_XMM.

52f6e28e9e Fix build with xcode4 and simplify GLOBAL.
Without this change I get link errors in firefox's libxul. It looks
like the linker expect a particular pattern for getting the GOT. This
patch changes webm to use the same pattern used by the compiler.

5cdc3a4c29 nasm: address labels 'rel label' vice 'wrt rip'
nasm does not support `label wrt rip', it requires `rel label'. It is
still fully compatible with yasm.

Provide nasm compatibility. No binary change by this patch with yasm on
{x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on
{x86_64,i686}-fedora13-linux-gnu have been checked as safe.

e114f699f6 nasm: match instruction length (movd/movq) to parameters
nasm requires the instruction length (movd/movq) to match to its
parameters. I find it more clear to really use 64bit instructions when
we use 64bit registers in the assembly.

Provide nasm compatibility. No binary change by this patch with yasm on
{x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on
{x86_64,i686}-fedora13-linux-gnu have been checked as safe.

746439ef6c Modify GET_GOT macro for performance.
GET_GOT was producing a zero length call.  This resulted in
pipeline flushes occuring when returing from the assembly
functions.  Masked on out of order cores, but evident on
Atom cores.

9f81463454 Fix a linker error on x86-64 Linux when not using a version script.
If the version script produced by the libvpx build system is not
 used when linking a shared library on x86-64 Linux, the constant
 data in the subpel filters produces R_X86_64_32 relocation errors
 due to the use of wrt rip addressing instead of
 wrt rip wrt ..gotpcrel.
Instead of adding a new macro for this addressing mode, this patch
 sets the ELF visibility of these symbols to "hidden", which
 allows wrt rip addressing to work without a text relocation.
This allows building a shared library without using the provided
 build system or a separate version script.
Fixes http://code.google.com/p/webm/issues/detail?id=46

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.

48c84d138f sse2 version of vp8_regular_quantize_b
Added sse2 version of vp8_regular_quantize_b which improved encode
performance(for the clip used) by ~10% for 32 bit builds and ~3% for
64 bit builds.

Also updated SHADOW_ARGS_TO_STACK to allow for more than 9 arguments.

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.
