Add mips64 support to the cmake build.
Requires use of new cmake toolchain file:
$ cmake path/to/aom -DCMAKE_TOOLCHAIN_FILE=path/to/aom/build/cmake/toolchains/mips64-linux-gcc.cmake
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.
