This CL introduces a new cpu package for CPU/platform feature detection. The cpu package is basically a copy of `internal/cpu` of the standard library. Revision: bf86aec25972f3a100c3aa58a6abcbcc35bdea49 This CL does not export ARM64 and PPC64 feature detection since at the moment ARM64/PPC64 requires standard library support.
