ECR #304775 - Preparation for kernel caching feature
1. Each device have a separate cache directory
2. It logs caching errors, so we can debug the cache and/or detect collisions
3. Implementeded cache size tracking, so we can evict old data when cache files are too large
4. Added file/path access permission control on both windows and linux
5. Have read/write file lock protection
6. -kcache-disable flag can be used to turn on/off the caching functionality
7. AMD_FORCE_KCACHE_TEST env variable is used for internal testing
8. For the stage we want to cache, call getCacheEntry() followed by makeCacheEntry() if the get fails; otherwise directly return cached data.
- After the compiler library code is refactored, getCacheEntry() and makeCacheEntry() will be wrapped into one function call, so that only one call is needed at the place we want to cache
TO DO:
1. Use it in the compiler library code
- Waiting for the decision on how many stages we want to cache, i) 1-stage caching: source->ISA; or ii) 3-stage caching: source->LLVM IR, LLVM IR->IL, IL->ISA
2. Tracking of timestamps for cache entries
- LRU eviction when cache grows too large
- Suggestion from Laurent: Regarding tracking timestamps for LRU eviction: Random eviction would probably perform as well as LRU and does not require timestamps.
3. Track cache entries per application

ECR #304775 - Move AMDExportKernelNature to compiler library.
This is part of the effort to move all extra passes out of the LLVM directory and into compiler library so we can build with a pure copy of LLVM. This is far from all of the sources required to move, but I'm trying to do the migration in moderately sized pieces.
Duplicates AMDSymbolNames.h utility header to avoid having a circular dependency between LLVM and compiler library. Eventually when all extra sources are moved into compiler library, there should only be one copy left.

EPR #419072 - [OpenCL2.0] Enable 16MB large on device queues
- Enable device queue creation up to 12MB. That should allow to run Intel SDK sample from the EPR that requires 6MB queue only.
- Currently a queue with >12.5MB size has a significant performance degradation. Thus the current max possible is 12MB. In general it's preferable to use the queue size more suitable for the task, rather than max possible.
