Includes some tricky manipulation of the locks for contexts and streams.
issue is that stealing a stream requires we lock the context to
walk the streams to find a victim. To avoid deadlock, we can't
have a stream locked when we lock the context. This implementation
releases the stream lock, then acquires the context and selects the
victim.
A more stable implemenation might be to copy the stream list
from a context so that a lock is not required to walk all streams.
Smart shared_ptr could be used to prevent the streams from being
deallocated during the walk.

CUBLAS API 7.5 now is supported by hipify;
API calls, which are not yet supported by hcblas/hipblas, are listed as HIP_UNSUPPORTED.
[ROCm/hip commit: 6ceb85a03a]
The differences from the similar scripts for hipify.pl:
1. CSV file with extended statistics is produced.
2. scripts' arguments are changed a bit:
DIRNAME [hipify options] [--] [clang options]
where -- is a delimiter; all the arguments are optional, except DIRNAME.
Usage example:
./hipexamine2.sh ./tmp -o-stats ./tmp/stats.csv -- -I/usr/local/cuda-7.5/include -I/usr/local/hipify-clang/hipblas/include 2>&1 | tee log
[ROCm/hip commit: bcbbc32fa6]
+ REPLACED bytes, TOTAL bytes & CODE CHANGED are added to statistics.
+ -o-stats option for specifying the file with statistic.

https://github.com/GPUOpen-ProfessionalCompute-Tools/HIP/issues/53
+ Unsupported refs (by HIP) are now might be listed along with the supported ones.
+ Warnings are added for the unhandled (by HIPIFY) refs, for instance:
"warning: the following reference is not handled: 'cublasContext' [param decl ptr]."
+ Reflect unsupported CUDA API refs in statistics.
+ Occupancy API [HIP_UNSUPPORTED].
+ A few CUBLAS refs are listed as HIP_UNSUPPORTED.
TODO: Statistics in CSV file.
[ROCm/hip commit: 3dd32e969d]
- hipFunction_t is now returned by value. This eliminates dynamic
allocation / memory management complexity in the module. Removed
the kernel
name so the structure is just 16 bytes now.
- Moved the hsa_executable_load_module and hsa_executable_freeze
calls to the hipModuleLoad and hipModuleLoadData calls.
- Apply sharedMemBytes in hipModuleLaunchKernel to group segment
size (not private).

- modified Makefile for hipblas_saxpy to replaced hcblas.so with hipblas.so as part of HCSWAP-100
- Resolved missing separator issue in peer2peer cookbook Makefile
