collect2: error: ld returned 1 exit status
For both GCN, nvptx, this each progresses ~25 'check-gcc-c++',
and ~10 'check-target-libstdc++-v3' test cases:
[-FAIL:-]{+PASS:+} [...] (test for excess errors)
..., with (if applicable, for most of them):
[-UNRESOLVED:-]{+PASS:+} [...] [-compilation failed to produce
executable-]{+execution test+}
..., or some 'FAIL: [...] execution test' where these test cases now FAIL when
attempting to use these interfaces, or, if applicable, FAIL due to run-time
'GCC/nvptx: sorry, unimplemented: dynamic stack allocation not supported'.

* config/gcn/unwind-gcn.c (_Unwind_RaiseException)
(_Unwind_Resume_or_Rethrow): New.
* config/nvptx/unwind-nvptx.c (_Unwind_RaiseException)
(_Unwind_Resume_or_Rethrow): Likewise.
