EPR #402000 - [CQE OCL][Perf][QR] ~6-7% perf drop in CompuCL Benchmark (Graphics: T-Rex subtest).
Add option to disable SC merge memory loads and stores. By default it is disabled. Will decide whether to enable it by default after performance runs.
cherrypick 1076590 and CL#1077419 from sc stg for adding option in sc.

EPR #405194 - Change unroll threshold to LLVM default to partially work around Linpack performance problem.
Prior to CL 1058428, which increased the unroll threshold to 200, this was only 100 which is lower than the LLVM default. Linpack's new ISA has increased register usage, but decreasing the unroll threshold to the previous level does not reduce the register count to its previous level. The increased register usage is probably a new SC problem, so this should probably be increased again in the future. There is no change in register usage with 100 vs. 150 on Linpack.

ECR #304775 - Bug 10112 - Raise default unroll threshold. The current default is 100, which is even lower than the LLVM default of 150. Increasing to 200 is a modest increase, and this should probably be even higher.

EPR #389586 - Add workaround for VI SPI SGPR initialization hardware bug for HSAIL path.
There is a hardware bug in VI (UBTS502672) which requires a workaround. Compute shaders need to tell shader compiler the available sGPR is 78 and set sGPUR usage in the compiled ISA to be 94. It has been done in AMDIL path but not done in HSAIL path. This change will apply the workaround to HSAIL path.
