This patch did a cleanup following the commit "Save NEON registers
in VP8 NEON functions". The pushing/poping of callee-saved NEON
registers was moved into individual NEON functions. Therefore,
we don't need to save those registers at the beginning of codec.
The related code was removed.

The recent compiler can generate optimized code that uses NEON registers
for various operations besides floating-point operations. Therefore,
only saving callee-saved registers d8 - d15 at the beginning of the
encoder/decoder is not enough anymore. This patch added register saving
code in VP8 NEON functions that use those registers.

This patch fixed errors reported in Issue 746: "dr memory VP8
encode errors" and Issue 745: "dr memory VP8 decode errors".
The "UNINITIALIZED READ" errors were fixed in x86 assembly
code. The list of files fixed is
vp8_intra_pred_uv_tm_sse2
vp8_intra_pred_uv_tm_ssse3
vp8_intra_pred_uv_ho_mmx2
vp8_intra_pred_uv_ho_ssse3
vp8_intra_pred_y_tm_sse2
vp8_intra_pred_y_tm_ssse3
vp8_intra_pred_y_ho_sse2

This patch fixed WebRTC Issue 3020: "Uninit error at
vp8_mbpost_proc_down_xmm". The first 8 values in d were not initialized,
but was accessed. This patch fixed c code as well as mmx and sse2 code.

significantly speeds up file generation.
the goal of this change is to convert rtcd.sh to perl as directly as
possible to allow for simple comparison. future changes can make it more
perl-like.

Filter out files ending in _neon.c and append .neon so the Android build
system knows to apply -mfpu=neon

The declaration of the bilinear filters specified an alignment clause
in the implementation file but not in the header. This turned out
to be harmless, but it did cause linker warnings to be emitted when
building on Windows.
The (extern) declaration in the header was changed, to match the
declaration in the implementation.

Jenkins warns on left shift of negative numbers and non-aligned read
of int. This commit fixed the two issues.

Adds a new end-usage option for constant quality encoding in vpx. This
first version implemented for VP9, encodes all regular inter frames
using the quality specified in the --cq-level= option, while encoding
all key frames and golden/altref frames at a quality better than that.
The current performance on derfraw300 is +0.910% up from bitrate control,
but achieved without multiple recode loops per frame.
The decision for qp for each altref/golden/key frame will be improved
in subsequent patches based on better use of stats from the first pass.
Further, the qp for regular inter frames may also be varied around the
provided cq-level.

this was never fleshed out in the context of VP8, for which it was
added. for VP9 it has no meaning.
