Adds the superres scale numerator, width, and height to the AV1_COMMON
struct for later use in encoding and decoding. This value will also be
added to the uncompressed frame header.

A #define statement is also added to represent the denominator - 16.

It is also not well integrated with speed_features.c, which is
the main reason for the removal.

Refactors the end of handle_inter_mode into a new funciton. This code
is responsible for calculating an accurate RD for the SIMPLE_TRANSLATION
motion mode in the simplest case, and does the same for other motion
modes as their experiments are enabled.

This patch aims to do as little as possible to the code inside the
function - that is left to later patches to reduce the complexity of
this diff.

Adds a dependent config flag 'interintra' to turn on/off interintra
modes altogether.
Adds a dependent config flag 'wedge' to turn on/off wedge compound
for both interinter and interintra.

Adds another macro to change wedge predictors to use
only 0, 1/2, or 1 weights.

From now, use
--enable-ext-inter --enable-wedge --enable-interintra to get the
same behavior as the old --enable-ext-inter.

This filter was temporarily removed due to test failures.
This patch reintroduces the filter and fixes two bugs:

* The test cases would occasionally segfault on x86, since
  the highbd filter requires its inputs to be aligned to
  16 bytes. This will always be true when used on real videos,
  so adjust the test cases to match.

* The function calc_block was incorrect for bit_depth > 8,
  due to passing an incorrect argument to _mm_srl_epi32().
  This was the cause of the original test failures.
