This was initialized from a const and never modified. But was still
passed around and stored in multiple structs.

Removed these 'rddiv' member variables and now RDOPT() and RDOPT_DBL()
always use the const RDDIV_BITS directly.

With C99 we can now declare iterators inside the 'for' statements,
allowing a better syntax for this macro.
This new syntax accepts #if/#endif inside the loop body,
and makes explicit, at loop body level, what the iterator name is.

This patch will not cause any performance change regardless of whether
speed_refs is on or off.

This coding tool is targeted to speed up the encoder side reference
frame selection process. The essential idea is to have two scanning
passes for each superblock of size 64x64 and this CL lays out the
initial framework but no reference frame selection is done yet:

First scanning pass - To simplify the partition and the mode
candidates (e.g. considering nearestmv / nearmv / zeromv only) and
identify the best reference frame prediction candidates;

Second scanning pass - Use the best reference frame candidate(s)
obtained from the first pass to encode the current superblock.

This moves up to the main the decision of which coding path to use,
aligning the decoder's logic on the encoder's logic.

The 'intra_y_mode_bsize_mask' speed feature is never set or

the tile boundary info flag was updated for each mi data structure
which starts from cm->mi. there is the second level buffer which
contains the pointer to the mi structure. it starts at
cm->mi_grid_visible. for every coded block, pointer in the second level
buffer only points to the top left mi structure of that particular coded
block. in order to get the correct boundary info for each mi. we have to
access the mi structure from cm->mi instead of cm->mi_grid_visible.
this change doesn't impact the result, it only cleans up the logic.

Before:
-------
accu_error was always <= 0:
- It was initialized to zero, and
- Became more and more negative through the iterations.

This meant that RDOPT() macro usage on accu_error was causing left shift
of negative value.

Now:
----
- accu_error is initialized to a large positive value.
- It becomes smaller on every iteration but remains >= always.

This is functionally equivalent: verified that there's no change in
output due to this patch.

Fix a bug where the encoder sets reference_mode =
COMPOUND_REFERENCE even if the frame contains some
4x4 blocks (but no larger blocks) that are single
reference. This occurs only in corner cases,
typically for very small frame sizes (e.g. 16x8).

Unifies the command line arguments for resize and superes.
Removes resize arguments that are currently unused.

Change-Id: I1362dffceb8257cee539f92679d1e8d79df08e66

Adds "superres-mode" and "superres-numerator" arguments to configure
superres scaling.

There are only two modes right now: SUPERRES_FIXED and SUPERRES_DYNAMIC.
0 sets the fixed mode and 1 sets the dynamic mode.

For the fixed mode superres will scale to the provided numerator where
possible. The cumulative scale change over resizing and superres is
limited to 1/2, so it may have to back off.

For the dynamic mode, the provided numerator will be used as the initial
numerator. Asides from that it's just random for now.

There were several places where loop_restoration used the encoded width
and height while superres was active. This patch changes it to use the
upscaled width and height, since loop_restoration is supposed to occur
after superres has done its upscaling.

This affects two places:
* Fixes a compile error with frame-superres when
  highbitdepth is disabled.
* Avoids including some supertx-related code when supertx
  is disabled
