MMX and X87 floating point instructions cannot be mixed freely on
the 32 bit x86 architecture.

This fixes a lot of unit tests in the 32bit build with
--enable-ext-intra.

- Optimization on tx_type: DCT_DCT, DCT_ADST, ADST_DCT, ADST_ADST.
- Overall encoder speed improves ~4.5%-6%.
- Update bit-exact unit test against current C version.

This commit fixes an encoding decision process issue that could
trigger enc/dec mismatch in the ext-inter experiment.

  Unit test shows manually developed SSE4.1 code would performs ~30%
  better if TXFM_2D_CFG configuration is set in lower level. This
  change only updates function signature. There is no performance
  impact.

This will facilitate bringing the zero node into the token set while
allowing its probability to vary independently.

x->blk_skip used to be uninitialized (leftover from encoding the
previous block), if cm->tx_mode != TX_MODE_SELECT (which is used with
higher --cpu-used or --rt options). This resulted in degraded coding
performance when using cm->tx_mode != TX_MODE_SELECT.

This fixes the VP10/EndToEndTestLarge.EndtoEndPSNRTest/40 unit test.

Also fixed an edge effect where encode_block in encodemb.c used the
formal width of the block (without cropping at the right edge), to
look up blk_skip, while select_tx_block in rdopt.c used the cropped
width to set blk_skip.

This commit handles the zero motion vector residuals for single
and compound reference modes, respectively. It improves the coding
performance by 0.13% with no additional encoding complexity.
