Benchmarking AMD's New AOCC Compiler For Ryzen

AOCC appeared to be only slightly faster than upstream Clang 4.0 for the C-Ray multi-threaded ray-tracer, but GCC remains much faster than Clang with this particular test.

Barely any different with AOCC using the Bullet physics library.

GCC remains faster than Clang with the FLAC audio encoding test.

In the single-threaded LAME MP3 encoding benchmark, the six tested compilers ran very close to the same speed.
