7317200002 Hybrid inverse transforms 16x16 AVX2 optimization 
- Add unit tests to verify the bit-exact result.
- User level time reduction (EXT_TX):
    encoder: 3.63%
    decoder: 2.36%
- Also add tx_type=V_DCT...H_FLIPADST SSE2 for 16x16 inv txfm.

d71a231c49 Add compiler warning flag -Wextra and fix related warnings. 
Note: some of these warnings are enabled by a combination of -Wunused
(added earlier) and -Wextra.

fdb60962f4 Fix warnings reported by -Wshadow: Part1: aom_dsp directory 
While we are at it:
- Rename some variables to more meaningful names
- Reuse some common consts from a header instead of redefining them.
