a169a4718b5b621f1770789e55eb8c441f7d0fcd c++, coroutines: Remove use of coroutine handle in the frame.
We have been keeping a copy of coroutine_handle<promise> in the state
frame, as it was expected to be efficient to use this to initialize the
argument to await_suspend. This does not turn out to be the case and
intializing the value is obstructive to CGW2563 fixes. This removes
the use.
gcc/cp/ChangeLog:
* coroutines.cc (struct coroutine_info): Update comments.
(struct coro_aw_data): Remove self_handle and add in
information to create the handle in lowering.
(expand_one_await_expression): Build a temporary coroutine
handle.
(build_actor_fn): Remove reference to the frame copy of the
coroutine handle.
(cp_coroutine_transform::wrap_original_function_body): Remove
reference to the frame copy of the coroutine handle.
