Fail faster if synchronization rules are violated.
Run vectorAddRevers to read last elements of array first - if the
vector add kernel starts before preceding copy finishes we
will read stale data and flag the error.
Increase default array sizes, so synchronization errors more easily
exposed.
This eliminates host-synchronization for null stream. Instead, the
null-stream uses GPU-side events to wait for other streams.
Default is OFF pending additional testing.
Add enhanced null-stream test.
Also refine HIP_TRACE_API.
Support hipHostMallocPortable flag.
Default flags are hipHostMallocPortable | hipHostMallocMapped.
Also:
-refactor tests to move addCount and addCountReverse into HipTest
namespace.
-test multi-GPU host memory.
- add checks for events across devices.
- refactor test to make sure it runs long enough to sensitive sync
techniques.
- add tests for DeviceSync, streamWaitEvent.
- use addOne kernel, use local initializer rather than init_array.
- use addOneReverse test to add from back of array. Test alternate fwd and backward to stress dependency logic.
- check device-side dependencies.

Use __device__ for all variables and functions to be used in kernel path
Abolish __device and adopt [[hc]] in HIP implementation, so __device__ can be
used on all HIP applications, no matter they are variables or functions.

XXX FIXME get around LDS spills caused in Promote-free HCC
hipDynamicShared2 uses all 64KB of LDS for computation. But in Promote-free HCC
there are cases where LDS spills would occur, which would make the test case to
hang.
In this workaround commit we reduce the size of dynamic LDS used to get around
this known issue, and will revert this commit when LDS spills are resolved in
HCC.

Changes to cope with Promote-free HCC
- abolish usage of address_space GNU attribute
- use __device in file-scope global variables which would be accessed by GPU kernels
- temporarily disable some math functions which take pointer arguments

- target "make test" will no longer build and run tests. It will only run the tests.
- added new target "make check" which will build and run the tests.
- target "make check" will build tests serially. Use -j<N> to build tests in parallel.
