This does not change the precision used for od_ec_enc_bool_q15
(used by aom_write and aom_write_bit), which means these two
paths will use different CDF precision for now.

The test that verifies that q15's code identically to CDFs
is disabled.

resolved subsequently.

Skip the quantization and reconstruction process when the best
selected intra mode goes with skip mode. Tested on a few 1080p
key frame coding at mid to high bit-rate range, the encoding
speed is up by 3% - 5%.

The compression for hdres key frame coding is improved from
neutural to 0.3% gains.

DECLARE_ALIGNED is not guaranteed by Visual Studio 2013/2015.
Unaligned buffers result in segmentation faults in the SSSE3 HBD
implementation, so alignment is still required.

In the decoder, the function get_tx_size_context() is called
by read_selected_tx_size(), *before* mbmi->ref_frame is set up.
This means that mbmi->ref_frame still holds the ref frames from
the previous block, and does not indicate if the current block is
inter or not.

Fortunately, all of the other functions called by read_selected_tx_size()
have an explicit "is_inter" parameter, which is set correctly.
So we can just plumb this through into get_tx_size_context().
