ECR #304775 - Bug 10752 kernel caching feature (AMDIL and HSAIL path)
1. For the stage we want to cache, call getCacheEntry() followed by makeCacheEntry() if the get fails; otherwise directly return cached data.
a. Each device have a separate cache directory
b. It logs caching errors, so we can debug the cache and/or detect collisions
2. Implementeded cache size tracking, so we can evict old data when cache files are too large
3. Added file/path access permission control on both windows and linux
4. Have read/write file lock protection
5. -kcache-disable flag can be used to turn on/off the caching functionality
6. AMD_FORCE_KCACHE_TEST env variable is used for internal testing
TO DO:
1. Tracking of timestamps for cache entries
-LRU eviction when cache grows too large
2. Track cache entries per application

ECR #333753 - Partial fix for Bug 10478 "Fix -fno-bin-llvmir/-fno-bin-hsail options"
If option -fno-bin-llvmi is set, .llvmir section is deleted from BIF on CG phase instead of FE. Both HSA & AMDIL are affected.
[Fixed] -fno-bin-llvm option causes clBuildProgram fail with error -11.
Took place only if compiled from OpenCL
[TODO] If possible -fno-bin-hsail should avoid putting HSAIL binary (BRIG) into BIF.
[Tests] pre check-in, make smoke, complib
[Reviewers] Brian Sumner, Nikolay Haustov
