This commit improves GCC’s handling of co_await when used with C++ member function pointers. A change in GCC version r13-9563 caused TARGET_EXPR to be used in get_member_function_from_ptrfunc, which conflicted with how flatten_await_stmt processes such expressions. This fix accommodates the reuse of TARGET_EXPR by flatten_await_stmt, resolving issues for coroutines involving member function pointers and co_await, as reported in PR121094 and PR117259.
