Attribute optimize(0) doesn't appear to be helpful helpful. This
prevents optimization in the function but not at call sites to the
function. The function may still be inlined since it has no side
effect (in some cases that we currently don't support).
Having a side effect prevents a call site optimization that allows
removal of a noinline function call with no side effect. Call site
optimization should only happen (in GCC at least) when using whole
program optimization so this may be stronger than we strictly need.
Also added _amdgpu_r_debug to the exported symbol list (global) and
switched to the standard macro for an exported symbol (HSA_API).
Without being in the global list the debugger will not find this
symbol if the binary has been stripped.

[ROCm/ROCR-Runtime commit: 299874f17d]
Makes malloc memory accessible to GPUs so that the memory has the
capabilities of the pool it is locked to.
This admits fine grained locked memory and reserves API space for any future
special CPU pools.

[ROCm/ROCR-Runtime commit: e0839ab27e]
1. Add hsa ext api hsa_amd_register_vmfault_handler for debugger to register callback in case of VM fault.
2. Extend hsa_ven_amd_loader API to:
(1) iterate loaded code objects in executable:
hsa_ven_amd_loader_executable_iterate_loaded_code_objects
(2) get loaded code object info:
hsa_ven_amd_loader_loaded_code_object_get_info
3. Make the id of hsa_queue the same as the one used in communication with thunk (for amd_aql_queue)

[ROCm/ROCR-Runtime commit: ce6aee01ed]
Added an API for creating signals with attributes.
Added two APIs for IPC operations on signals.
Initial use of exceptions for error handling.
Add ref counting to signals.
Removed spin loops from signal destructors.
Signals are no longer to be destroyed with delete, use DeleteSignal instead.
Added delete safety to doorbells.
Added secondary hsa_signal_t -> Signal* translation path for IPC enabled signals.
