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.

ECR #333753 - ORCA RT/Compiler Lib/aoc2: AMD HSA Code Object Import feature (part II) - arbitrary hidden (extra) kernargs support
Only HSAIL path is affected. It doesn't affect blit kernels.
To use offline by aoc2:
aoc2 -hsacodeobject=<importing_code_object_filename> -numhiddenkernargs=<num> -cl-std=CL2.0 -march=hsail(-64) -mdevice=Bonaire <source_cl_filename>
To use online by setting env:
AMD_DEBUG_HSA_NUM_HIDDEN_KERNARGS=<num>
where num >= 0. If num == 0, then no additional arguments will be added on RT for every kernel. The default value is unchanged and equal to 6 for now.
Misc:
+ get rid of PRE & POST defines in Compiler Lib, as they started to conflict with ugl\gl\gs\hwl\ headers with the same defines.
+ minor copy/paste eliminations & typo fixes
+ ocltst complib tests update
Testing: pre check-in, manually based on ocl sdk MatrixMultiplication

ECR #333753 - ORCA RT/Compiler Lib: HSA Code Object/RT independent loader introducing/integration into OpenCL.
Changes by Evgeniy Mankov.
Purpose:
Use the same Finalizer & loader for both HSA & ORCA RT.
AMDIL path is not affected.
Changes:
1. The whole BRIG is finalized now instead of per kernel finalization (both in gpuprogram & hsail_be).
2. HSALoader is changed in order to work with CodeObject and new HSA Loader's API <96> Context. Now it is in ORCA<92>s gpuprogram instead of Compiler Lib.
3. brig_loader.cpp is removed from compiler lib, as well as __aclHSALoader function exports from the whole stack.
4. BIF .text section now contains the whole finalized HSA CodeObject instead of separate symbols for finalized kernels.
5. ORCA RT now works directly with amd_kernel_code_t and doesn't need any SC metadata anymore.
6. aoc2 is supplemented with fake offline loader correspondingly.
7. amdocl/complib make sytem changes.
8. test_driver.pl update.
ToDo:
1. Implement disassemble() & BuildLog() functions to support ISA dumping & SC error handling (Konstantin).
2. Global variables initialization by pragma reference (Konstantin). Test to verify: test_basic progvar_prog_scope_init.
3. Code Object without kernels support (Nikolay - ready). Test to verify: test_generic_address_space.exe library_function
testing: windows smoke, pre check-in, ocl conformance 2.0, ocl SDK 2.9

Improved adptation by changing waves/simd only when the last change has been enforced. Also detecting discontinuities in measured data and discard them.
