Jonathan R. Madsen 90ff7188f8 Crusher hackathon updates (#164)
- improved error handling in dyninst
- improved error handling in omnitrace exe
- new logging facility for omnitrace exe
- improved backtraces
- disable concurrent kernels in rocprofiler
- updates `setup-env.sh` and modulefile
  - set `omnitrace_ROOT`
  - set `HSA_TOOLS_LIB` if roctracer or rocprofiler enabled
  - set `ROCP_TOOL_LIB` if rocprofiler enabled
  - closes #163 
- No longer make setting `HSA_ENABLE_INTERRUPT=0` the default 
  - this has performance implications
- this was set to workaround a bug in ROCR which caused an ioctl call in
ROCm to hang when interrupted. But it was only interrupted when realtime
sampling was enabled since the CPU-clock doesn't increment when waiting
  - This bug should be fixed in ROCm 5.3
- omnitrace no longer activates a realtime sampler by default when
sampling, thus this bug is no longer encountered unless the user
explicitly triggers realtime sampling
