coroutines: Improve diagnostics for one allocator case.
If the user provides operator new and that is noexcept, this
implies that it can fail with a null return. At that point, we expect
to be able to call get_return_object_on_allocation_failure().
This diagnoses the case where such an operator new has been
provided, but the g-r-o-o-a-f is either missing or unusable.
gcc/cp/ChangeLog:
* coroutines.cc (morph_fn_to_coro): Diagnose unavailable
get_return_object_on_allocation_failure.
gcc/testsuite/ChangeLog:
* g++.dg/coroutines/coro-bad-grooaf-01-grooaf-expected.C: New test.
