amdgcn: Adjust failure mode for gfx908 USM
Unified Shared Memory does not appear to work well on gfx908, which is why we
disabled xnack by default. For this reason it makes sense to inform the user
as compile time, but this is causing trouble in the testsuite which assumes
that USM only fails at runtime.
This patch changes the gfx908 compile time message to a warning only (in case
some other target does this differently), and prevents the tests from
attempting to run in host-fallback mode (given that that is not what they are
trying to test). It also changes the existing warning to only fire once.
The patch assumes that effective target "omp_usm" also implies self-maps.
gcc/ChangeLog:
* config/gcn/gcn.cc (gcn_init_cumulative_args): Only warn once.
Use "required" instead of "enabled" in the warning.
* config/gcn/mkoffload.cc (process_asm): Warn, don't error.
Use "required" instead of "on" in the warning.
libgomp/ChangeLog:
* testsuite/lib/libgomp.exp (check_effective_target_omp_usm): New.

working Unified Shared Memory to run the test.
