Replaces resizing's table and index approach to frame sizes with
numerator and denominator integers in the AV1_COMP struct.

This approach is more flexible and will be simpler going forward as it
is much more similar to the 1-pass CBR approach that is also being
refactored. The intention is to merge both approaches and this is the
first step toward that.

Make row indexed at 192/96 equal to the one indexed at 191/95, 
so that clamping the table address to 191/95 produces results 
consistent with the libaom implementation. 

New change to replace 10692 which was reverted in 10870.

It's an obsolete experiment.

Change-Id: I0461b174875b4db0bcf3da643f8b2e97ad2fab51

The frame superresolution experiment currently makes no use of the
features of the loop restoration experiment. While this is planned for
the future, there is no reason to continue having frame superresolution
depend on loop restoration for now.

Frame superresolution was made dependent by having every preproccesor if
containing its config flag also depend on the loop restoration config
flag. Those if's are modified to only check the frame superresolution
flag by this patch.

Patch https://aomedia-review.googlesource.com/c/10901/ temporarily
disabled the SSE2 warp filter for 4x4 blocks, because of a
data race when the filter was used at the right-hand edge of a
tile in a multithreaded encode.

This patch fixes the data race and re-enables the SSE2 warp filter.

There was a bug caused by the following sequence of events:
* A frame was coded full-size, filling out the
  cm->above_context array as normal.
* The next frame was coded at a reduced size
* Due to changes between VP9 and AV1, we now clear the
  context arrays per-tile on the decoder side. The amount
  cleared is the span of the tile, rounded up to the next
  mi unit. Since this frame is at a reduced size, this
  leaves some entries "off the edge of the frame" set to 1.
* get_entropy_context() reads a full transform block's worth
  of data from cm->above_context. This could read the off-frame
  1s, even when all the in-frame values were 0 (eg, because
  we're working on the topmost block of the frame).
* This leads to the decoder getting the wrong context, causing
  an encode/decode mismatch.

We fix this by rounding up to the next superblock, rather than
the next mi unit, when clearing the context arrays per-tile.
This is safe because all tiles other than the rightmost column
must be an integer number of superblocks wide.
