Hi
In captures_temporary, the current implementation fails to handle
component_ref. This causes ice with case co_await A while
operator co_await is defined in base class of A. Also it is necessary
to capture the object of base class as if it is temporary object.

This patch strips component_ref to its base object and check it as usual.

Bootstrap and test on X86_64, is it OK?
