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.

The RSA Data Security, Inc. implementation license bears a requirement
similar to the old problematic BSD license with advertising clause.

Commit 3245d463 "ivfenc: support reading/writing from a pipe" broke
support for two pass encodes of raw files when done in two
invocations of ivfenc. The raw image was only set up on pass 0,
which was never hit when running with --pass=2 --passes=2.

This patch addresses issue #79, which is a regression since commit
28de670c "Fix RD bug." If the coded error value is zero, the iiratio
calculation effectively multiplies by 1000000 by the
DOUBLE_DIVIDE_CHECK macro. This can result in a value larger than
INT_MAX, giving a negative ratio. Since the error values are
conceptually unsigned (though they're stored in a double) this patch
makes the iiratio values unsigned, which allows the clamping to work
as expected.

Use - for the filename to use stdin/stdout. Update to avoid opening
the file multiple times.

Typo caused C version of 16x16x4 SAD to be called when built with
--disable-runtime-cpu-detect.

ssim.c comiles in a huge (512M) amount of global scratch space. Allocating
this data on the heap would be a better solution, but this file doesn't
need to be built at all in most cases, so as a first pass, disable it
except when doing opsnr.stt output (--enable-psnr).

XMM6 to XMM15 are non-volatile on Windows x64 ABI.  We have to save
these registers.

No good reason to be tricky here. I don't know why 'break' occurred to me
as the natrual replacement for the 'return', but an if/else block is
definitely clearer.

The new scheme introduced in I68d35a2f did not clamp chroma MVs in the SPLITMV
 case, and clamped them incorrectly (to the luma plane bounds) in every other
 case.
Because chroma MVs are computed from the luma MVs before clamping occurs, they
 could still point outside of the frame buffer and cause crashes.
This clamping happens outside of the MV prediction loop, and so should not
 affect bitstream decoding.

Vestigial.

Updated the comment in change I6bef2ab5, but missed adding the code to

Restructure vp8_sixtap_predict functions to eliminate extra 5-line
calculation while doing first-pass only. Also, combline functions
to eliminate usage of intermediate buffer. This gives decoder a 3%
performance gain on my test clips.

Using uname fails e.g. on a 64-bit machine with a 32-bit toolchain.
The following gcc -dumpmachine strings have been verified:
 * 32-bit Linux gives i486-linux-gnu
 * 64-bit Linux gives x86_64-linux-gnu
 * Mac OS X 10.5 gives i686-apple-darwin9
 * MinGW gives mingw32

*darwin8* and *bsd* can safely be assumed to be correct, but *cygwin*
is a guess.

This patch removes the secondary MV clamping from the MV decoder. This
behavior was consistent with limits placed on non-split MVs by the
reference encoder, but was inconsistent with the MVs generated in the
split case.

The purpose of this secondary clamping was only to prevent crashes on
invalid data. It was not intended to be a behaviour an encoder could or
should rely on. Instead of doing additional clamping in a way that
changes the entropy context, the secondary clamp is removed and the
border handling is made implmentation specific. With respect to the
spec, the border is treated as essentially infinite, limited only by
the clamping performed on the near/nearest reference and the maximum
encodable magnitude of the residual MV.

This does not affect any currently produced streams.
