* Adding AOCC compiler to SPACK community
The AOCC compiler system offers a high level of advanced optimizations, multi-threading and processor support that includes global optimization, vectorization, inter-procedural analyses, loop transformations, and code generation. AMD also provides highly optimized libraries, which extract the optimal performance from each x86 processor core when utilized. The AOCC Compiler Suite simplifies and accelerates development and tuning for x86 applications.
* Added unit tests for detection and flags for AOCC
* Addressed reviewers comments w.r.t version checks and url,checksum related line lengths
