    c++, coroutines: Allow convertible get_return_on_allocation_fail
[PR109682].

    We have been requiring the get_return_on_allocation_fail() call to have the
    same type as the ramp.  This is not intended by the standard, so relax that
    to allow anything convertible to the ramp return.

            PR c++/109682

    gcc/cp/ChangeLog:

            * coroutines.cc
            (cp_coroutine_transform::build_ramp_function): Allow for cases
where
            get_return_on_allocation_fail has a type convertible to the ramp
            return type.

    gcc/testsuite/ChangeLog:

            * g++.dg/coroutines/pr109682.C: New test.
