Call the individually optimized horizontal and vertical functions. This
implementation abuses the temp buffer.
This will be replaced with a custom optimized function.
Over 2x speedup.

Adding missed parenthesis around boolean expressions. Bitstream is changed.
Regenerating test vectors.

Super basic conversion from the other implementations. Any changes to
one should be trivial to copy over keep in sync.

Independent horizontal and vertical implementations.
Requires that blocks be built from 4x4 and [xy]_step_q4 == 16
6-10% improvement. CIF improved the least.

It does encodings with min and max q set at 0, and check to make sure
output PSNR at MAX_PSNR (100).

In the rare case were 4x4 interior filtering was called for but no
8x8 or larger filtering takes place, the previous code was skipping
the filtering. This patch fixes the issue by including the interior
mask in the overall mask for the filter application loops.

This commit enables 8x8 DCT and hybrid transform unit tests. It
also tunes the forward hybrid transform rounding opertions for
more precise round-trip performance.

For cases where there's no transform set in bit 0 (the left edge of
the SB) but bit 0 of mask_4x4_int is set (the edge 4 pixels from the
left edge needs filtering), it was incorrectly being skipped before.
This situation only happens on the leftmost edge of the image, as
the edge at column 0 is intentionally skipped since there aren't
pixels to the left to read.

Encoding of bus @ 1500kbps (first 50 frames) goes from 3min57 to
3min35, i.e. approximately a 10.5% speedup. Note that the SIMD versions
which use a bilinear filter (x_offset & 7 || y_offset & 7) aren't
perfectly interleaved, and can probably be improved further in the
future. I've marked this with a few TODOs/FIXMEs in the code.
