c++: co_await and initializer_list [PR103871]
When flatten_await_stmt processes the backing array for an initializer_list,
we call cp_build_modify_expr to initialize the promoted variable from the
TARGET_EXPR; that needs to be accepted.
PR c++/103871
PR c++/98056
gcc/cp/ChangeLog:
* typeck.cc (cp_build_modify_expr): Allow array initialization of
DECL_ARTIFICIAL variable.
gcc/testsuite/ChangeLog:
* g++.dg/coroutines/co-await-initlist1.C: New test.
