The range_check is not used because the bit range
in fdct# is not correct. Since we are going to merge in a new version
of fdct# from nextgenv2, we won't fix the incorrect bit range now.

This commit limits the scope of 1-D DCT and ADST functions within
vp9_dct.c and makes them static. This largely clears out the cross
referencing issue between vp9_dct.c and the SIMD optimizations.

This change is made in preparation for a
subsequent patch which adds acceleration
for the highbitdepth transform functions.

The highbitdepth transform functions attempt
to use 16/32bit sse instructions where possible,
but fallback to using the C implementations if
potential overflow is detected.  For this reason
the dct routines are made global so they can be
called from the acceleration functions in the
subsequent patch.

(cherry picked from commit 454342d4e77dbb67f4a3c10f97a57a6fcb46d9a0)

This commit reworks the forward transform and quantization process
for 8x8 block coding. It combines the two operations in a single
function to save a store/load stage of the original transform
coefficients. Overall the speed -6 is slightly faster (around 1%
range). The compression performance of speed -6 is improved by
3.4%.

Uses highbd_ prefix convention consistently.

Change-Id: I58f7f799a7ff8e32701bcd71c955bcf1cdd4581e

Adds various high bitdepth transform functions and tests.
Much of the changes are related to using typedefs tran_low_t
and tran_high_t for the final transform cofficients and intermediate
stages of the transform computation respectively rather than fixed
types int16_t/int. When vp9_highbitdepth configure flag is off,
these map tp int16_t/int32_t, but when the flag is on, they map
to int32_t/int64_t to make space for needed extra precision.

This commit fixes the scaling factors used in the C versions of the
DC calculation functions.

This commit enables a fast path computational flow for forward
transformation. It checks the sse and variance of prediction
residuals and decides if the quantized coefficients are all
zero, dc only, or more. It then selects the corresponding coding
path in the forward transformation and quantization stage.

It is currently enabled in rtc coding mode. Will do it for rd
coding mode next.

In speed -6, the runtime for pedestrian_area 1080p at 1000 kbps
goes down from 14234 ms to 13704 ms, i.e., about 4% speed-up.
Overall coding performance for rtc set is changed by -0.18%.

This commit adjusts the forward 16x16 DCT computation steps to
