Sean Keely 0e17cc2887 Allow reducing max occupancy (max scratch waves) when applications request large amounts of scratch.
Also emit error messages to stderr if no async queue error callback was registered and queue fault messages are enabled (on by default).
Queue fault messages are controlled with env key HSA_ENABLE_QUEUE_FAULT_MESSAGE.

Sean Keely 1bc15bbf79 Switch atomic_helpers.h from C11 atomics to GCC __atomic builtins.
C11 atomics are not statically guaranteed to be lock free and so
may not be atomic with respect to atomic operations originating
outside the standard library, such as platform atomics.

C11 macros to statically discover always lock free operations
(ATOMIC_*_LOCK_FREE) do not cover uint64_t in GCC and
std::atomic<uint64_t> is not a type alias of any covered type.

All use of __atomic by atomic_helpers.h is statically checked to be
always lock free.

GCC builtin fencing does not appear to be strong enough for WC memory.
Added an option (enabled) to enforce consistency for WC memory on x64.

__sync builtin's were not used as they were declared legacy by GCC.

Added a strongly conservative option (ALWAYS_CONSERVATIVE) to enable
use of full memory fences in place of partial fences and compiler
driven processor specific optimization.

Jay Cornwall acc5f15e4c Enable VM fault message by default on Linux
This option was disabled by default to address issues writing to stderr
in Windows applications. The lack of an error message for memory access
faults is confusing to users, however.

Enable the error message by default on Linux only.
