This fixes crashes due to infinite recursion when var_tx,
ext_tx and rect_tx are enabled without cb4x4. This
is the first part of an ongoing fix for this experiment
interaction.

Adds the CfL experiment flag and computes a block-level DC_PRED that is
required by CfL in order to compute alpha_cb and alpha_cr.

The rate-distorsion impact of computing DC_PRED at the prediction block level
for chroma planes is rather small

Change-Id: Id714ece4ca672ac2a6beabca32a5fa30d83c8231

ported from libvpx:

Added casts to remove warnings:

In regards to the safety of these casts they are of two types:-

- Normalized bits per (16x16) MB stored in a 32 bit int (This is safe as
  bits per MB even with << 9 normalization cant overflow 32 bits. Even
  raw 12 bits hdr source even would only be  29 bits :- (4+4+12+9) and
  the encoder imposes much stricter limits than this on max bit rate.

- Cast as part of variance calculations.  There is an internal cast up
  to 64 bit for the Sum X Sum calculation, but after normalization
  dividing by the number of points the result will always be <= the SSE
  value.

This reverts commit c92c6e9d.

Reason for revert:

The lowbd version of the function is called even with CONFIG_HIGHBITDEPTH
on, when bit depth == 8. And that particular case will not work as
before with this change.

Only differences:
- Initial values of 'out_ptr' were different.
- Macros used to load g13, g15, g5 and g7 were different, but they were
actually equivalent.

This reverts commit 8cd0e7ef.

Reason for revert:
This change breaks av1_warp_affine_c when CONFIG_HIGHBITDEPTH is enabled.

In particular, running ./test_libaom --gtest_filter=*Warp* compiled with --enable-warped-motion --enable-highbitdepth shows several test failures, followed by a segmentation fault when it gets up to test SSE2/AV1WarpFilterTest.CheckOutput/4

The tricky part is that the use the lowbd version of the function is dependent on a mix of two conditions:
(1) Compile time check for CONFIG_HIGHBITDEPTH and
(2) Run time check to see if bit-depth == 8
So, it is tricky to refactor.
