coroutines : Adjust constraints on when to build ctors [PR98118].
PR98118 shows that TYPE_NEEDS_CONSTRUCTING is necessary but not
sufficient. Use type_build_ctor_call() instead.
gcc/cp/ChangeLog:
PR c++/98118
* coroutines.cc (build_co_await): Use type_build_ctor_call()
to determine cases when a CTOR needs to be built.
(flatten_await_stmt): Likewise.
(morph_fn_to_coro): Likewise.
gcc/testsuite/ChangeLog:
PR c++/98118
* g++.dg/coroutines/pr98118.C: New test.
