Use higher precision offsets for more accurate predictor
generation when references are at a different scale from
the coded frame.

Change-Id: I4c2c0ec67fa4824273cb3bd072211f41ac7802e8

Implements the high precision Wiener filter with an offset
to reduce the error due to saturation without increasing
the number of bits needed for intermediate precision.

Also turns the high precision filter on.

Add SSE2 lowbd and SSSE3 highbd versions of the filters
introduced in https://aomedia-review.googlesource.com/c/11962/ .

These filters are equivalent in speed to the SSE2 implementations
of the regular convolve filter. The average time to filter a
64x64 block is:

lowbd C: 52us
lowbd SSE2: 5.6us
highbd C: 53us
highbd SSSE3: 5.8us

Also add a correctness test based on the warp filter tests.

Rename '--enable-aom-highbitdepth' to '--enable-highbitdepth'

Change-Id: I1de13c3508c30c552532993419d8ace326142ab6

The convolve filters generated by loop_wiener_filter_tile
are not compatible with some existing convolve implementations
(they can have coefficients >128, sums of (certain subsets of)
coefficients >128, etc.)

So we implement a new variant, which takes a filter with 128
subtracted from its central element and which adds an extra copy
of the source just before clipping to a pixel (reinstating the
128 we subtracted). This should be easy to adapt from the existing
convolve functions, and this patch includes SSE2 highbd and
SSSE3 lowbd implementations.

It in essence refactors the code for both the interpolation
filtering and the convolution. This change includes the moving
of all the files as well as the changing of the code from vp9_
prefix to vpx_ prefix accordingly, for underneath architectures:
(1) x86;
(2) arm/neon; and
(3) mips/msa.
The work on mips/drsp2 will be done in a separate change list.

this macro was used inconsistently and only differs in behavior from
DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
is used with calls to assembly, while generic c-code doesn't rely on it,
so in a c-only build without an alignment attribute the code will
function as expected.

Change-Id: I58f7f799a7ff8e32701bcd71c955bcf1cdd4581e

Incorporates the WRAPLOW macro into the non-highbitdepth transforms
to aid hardware verification between a software C model and an
intended hardware implementation though the use of the configure
options: --enable-experimental --enable-emulate-hardware.
Note that to avoid further discrepancies between the sse/sse2
implementations of the transforms and the C implementation, when the
emulate hardware option is invoked, we also disable sse/sse2/etc.

Also incudes some minor cleanups/renaming etc.

There is a normative scaling range of (x1/2, x16)
for VP9. This patch fixes the maximum downscaling
tests that are applied in the convolve function.

The code used a maximum downscaling limit of x1/5
for historic reasons related to the scalable
coding work. Since the downsampling in this
application is non-normative it will revert to
using a separate non-normative scaler.

- Intermediate height was not correct i.e. when block size is 4 and
  y_step_q4 is 6. In this case intermediate height was
  (4*6) >> 4 = 1 and vertical interpolation needs two source pixels
  plus 7 extra pixels for taps.
- Also if the current output block is 16x16 and we are using 4x upscaling
  we need only 12 rows after horizontal filtering instead of 16.

  Patch Set 2: Intermediate_height updated after CL 66723
               "Fix bug in convolution functions (filter selection)"
