Current x86inc.asm didn't handle 32bit PIC build properly.
TEXTRELs were seen in the library built. The PIC macros from
libvpx's x86_abi_support.asm was used to fix this problem.
The assembly code was modified to use the macros.

Notes: We need this fix in for decoder building. Functions in
encoder will be fixed later.

Jenkins was failing to detect the case where an existing
file is recreated with new content. In this case, thinking
that the file already existed, Jenkins did not re-copy the
file as it should have.

By adding the file test-data.sha1 as a dependendency to
the LIBVPX_TEST_DATA build target the files will be
recopied if the MD5 of an existing file changes.

This could be further improved to only copy files that
have changed rather than copying the whole set as done in
this patch.

(Thanks to jzern@ who diagnozed ithe problem and suggested
this fix).

The commit added reset of pred_mv at the beginning of each SB64x64
partition mv search, also limited the usage of pred_mv only when
search on the largest partition is already done. This is to fix
a crash at speed 1/2 encoder where an invalid mv is used in mv
search.

This commit enables adaptive constraint on motion search range for
smaller partitions, given the motion vectors of collocated larger
partition as a candidate initial search point.

It makes speed 0 runtime of bus at CIF and 2000 kbps goes from
167s down to 162s (3% speed-up), at 0.01dB performance gains. In
the settings of speed 1, this makes the runtime goes from 33687 ms
to 32142 ms (4.5% speed-up), at 0.03dB performance gains.

Compression performance wise, it gains at speed 1:
derf  0.118%
yt    0.237%
hd    0.203%
stdhd 0.438%

The CpuSpeedTest is extended to cover 2pass good quality with CpuUsed

Mis-merge of the following change managed to break mode order
and delete two mode options (new alt ref and near alt ref)
It also created a situation where we could test two undefined
modes off the end of the VP9_mode_order[] data structure.

Lots of TODO which will be taken care in upcoming changes. As is,
about 6x faster than C version.

Removes this speed feature since it is very slow and unlikely
to be used in practice. This cleanup removes a bunch of unnecessary
complications in the outer encode loop.

Reformatted version of a patch submitted by Erik/Tamar
from Intel.  For the test clips used, the decoder
performance improved by ~2%.

Change-Id: Ifbc37ac6311bca9ff1cfefe3f2e9b7f13a4a511b

Propose some changes to the speed 2 settings to improve quality.
In particular, turns off the adjust_thresholds_by_speed feature
which improves results by 6%. Also removes the code for
adjust_thresholds_by_speed since it conflicts with the adaptive
rd thresh feature.

Overall, with this change speed 2 is -15.2% from speed 0 settings,
on derf, which is significantly better than -21.6% down before.

mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of pointers to MODE_INFO structs.  The
MODE_INFO structs are now stored as a stream (decoder only),
eliminating unnecessary copies and is a little more cache
friendly.
