AMD AOCC 4.0 vs. GCC vs. LLVM Clang Compiler Benchmarks On Zen 4

Coremark was one of the rare tests where the AOCC 4.0 built binary came in last place.

There was also a surprising performance regression with C-Ray built under AOCC 4.0.

AOCC 4.0 was producing the fastest binary for AVIF image encoding.

The AOCC built oneDNN neural network library often was coming out in front but by very slim margins.
