      Fix DAALA_EC when EC_MULTISYMBOL disabled. · 0f11c78d
      Nathan E. Egge authored 
      When DAALA_EC is enabled, calls to aom_read_tree() and aom_write_tree()
 would automatically convert the aom_tree_index and aom_prob into a CDF
 and call the aom_read_cdf() or aom_write_cdf(), which causes an
 error if DAALA_EC is enabled without EC_MULTISYMBOL.
This patch moves the conversion functions from daalaboolreader.h and
 daalaboolwriter.h into bitreader.h and bitwriter.h respectively, and
 only calls the conversion functions if EC_MULTISYMBOL is enabled.
This allows DAALA_EC to be enabled without EC_MULTISYMBOL and is a
 bitstream change when both ANS and EC_MULTISYMBOL are enabled as calls
 to read and write trees will automatically be converted into calls that
 read and write cdfs.

      Correct cmake intrinsic flag translation. · 0b3c9052
      Tom Finegan authored 
      MSVC only. Use the AVX/AVX2 flags only for AVX and AVX2. Ignore
the SSE flags since they're not needed with MSVC.

      Speed up global motion determination · 15338d5f
      David Barker authored 
      When global-motion is enabled, a considerable amount
of encoder time is spent in the functions in corner_match.c.
This patch optimizes those functions to be 3.5-4x as fast,
leading to an end-to-end encoder speed improvement
(on 20 frames of tempete_cif.y4m) of:

 200kbps: ~26% faster
 800kbps: ~19% faster
2800kbps: ~12% faster

      Add flag for RAWBITS to use raw bits with DAALA_EC. · 24f1a904
      Nathan E. Egge authored 
      The use of raw bits is now disabled by default and can be turned on with:
 ./configure --enable-experimental --enable-rawbits
This commit has a negligible impact on rate.
