Confirmed: flag_trampolines matters only for calls with the ECF_BY_DESCRIPTOR
bit set or CALL_EXPR_BY_DESCRIPTOR being true. Other than from the Ada backend,
such calls are generated only from gimple nodes with subcode bit
GF_CALL_BY_DESCRIPTOR set. GF_CALL_BY_DESCRIPTOR gets set through
gimple_call_set_by_descriptor with argument true, and such calls exist only as
consequence of tree nodes with CALL_EXPR_BY_DESCRIPTOR being true.
