Includes reordering and other clamping changes, as well as
changes to reduce multiplier precision.
cam_lowres (60 frames): -0.092% BDRATE improvement in
--disable-cdef --disable-global-motion --disable-ext-tx
configuation.

This reverts commit 79b78b7d47.
The transform coefficient range needs some more tuning.
Before we finalize on that front, directly applying clamping
would cause multiple unit test failure issues. Hence revert
this Cl temporarily.

When --enable-coefficient-range-checking isn't specificed, clamp the
coefficient at each stage.
This doesn't change the decoder behaviour for existing AV1 streams.
However, some AV1 bitstreams that would have been rejected by the
decoder as illegal (range check failure) are now legal bitstreams.
There is no impact on video quality.

The highbd_clip_pixel_add() function is generalized to be used in
the regular 8 bit path. Move its defintions outside the highbd
experimental flag.
This resolves the comiler warning in unit tests when high bit-depth
is turned off.

Since we now require C99, this is undefined behavior.
Thanks to Luc Trudeau for the report and Alex Converse for the
suggestion on how to make the macro safe for all integer sizes.
