Clear JIT cache on exit (#1518)
* Initial cache memory allocator implementation
* Get rid of CallFlag
* Perform cache cleanup on exit
* Basic cache invalidation
* Thats not how conditionals works in C# it seems
* Set PTC version to PR number
* Address PR feedback
* Update InstEmitFlowHelper.cs
* Flag clear on address is no longer needed
* Do not include exit block in function size calculation
* Dispose jump table
* For future use
* InternalVersion = 1519 (force retest).
