present. Currently requires only necessary x86 object
formats and the presence of the -Ox opt mode arg.

Earlier, intra prediction for rectangular blocks was performed by
running two steps of prediction on square sub-blocks.
With this experiment, we do proper intra prediction for rectangular
blocks. This ensures that we make use of all available neighboring
pixels especially for directional modes. For this, all the intra
predictors were updated to work with rectangular transform block sizes.
Performance improvements are small but free of cost:
All Intra frames:
lowres: -0.126
midres: -0.154
Video Overall:
lowres: -0.043
midres: -0.100

We no longer support armv6 and the corresponding
optimized source files have been removed. This
commit removes support for the target and its
media instruction set extensions from the build
system as well.
Once armv6 jobs are removed from the integration
config we can start rejecting --enable/disable-media.
Also reject --enable-edsp.

Libvpx dropped armv6 support sometime after the aom fork.
We don't intend to support this platform, which is likely
too slow in any case. Remove the assembly and intrinsics
optimized routines, their tests, cpu feature detection,
and rtcd specialization for this instruction set extension.

Supporting Emscripten requires modification of all uses of the
target_link_libraries() function to match the form
of the target_link_libraries() call in Emscripten.cmake.
The AOM_LIB_LINK_TYPE variable has been added to allow for
flexibility on the libaom side when using toolchains that
behave similarly to Emscripten.cmake wrt
target_link_libaries().
To use CMake for an Emscripten build, first install Emscripten, then:
$ cmake path/to/aom -DCMAKE_TOOLCHAIN_FILE=path/to/Emscripten.cmake -DAOM_TARGET_CPU=generic

This reverts commit a8b97eb513.
Reason for revert: There are still a few warnings related to this in
the base configuration. Reverting this to avoid breaking new patches.

This experiment complexifies DSP function dispatch, without bringing
any real value (it's non-normative arbitrary behaviour).
Moreover, it only has an effect on obsolete transforms, the new ones
don't implement this mechanism.

MSA is supported via addition of -DENABLE_MSA=1. Support for i6400
and p6600 targets can be enabled by passing -DMIPS_CPU=i6400 and
-DMIPS_CPU=p6600 respectively.

A similar cleanup happened before, but the empty statements have since
reappeared. I added a check in 'specialize' subroutine to die whenever
such an empty specialize call is found, so that config+make would fail.
