- First pass encoding time reduces ~10.9% on i7-6700
  at 100 frames, 1080p.
- avx2 works for coeff number >= 8 cases; coeff number < 8
  case will be implemented by sse2.
- Unit test is added type B/FP/DC.

Scale the rounding factor according to the scaling factor applied
to the quantization step size. This resolves a compression
performance regression in 32x32 and above transform size.

- Add av1_build_quantize() function so that quantization
  related unit test would be able to access quant/dequant
  table without starting an encoder instance and directly
  accessing cpi.

Previously, we assumed that av1_init_plane_quantizers is always called with
segment_id == xd->mi[0]->mbmi.segment_id (and use the latter to derive the value
of 'qindex' to use in the quantizer). But this is no longer true when supertx
is enabled. This patch instead remembers the value of 'qindex' derived from
the latest call to av1_init_plane_quantizers and uses that directly.
