    c++: missing aggregate base ctor [PR102045]

    When make_base_init_ok changes a call to a complete constructor into a =
call
    to a base constructor, we were never marking the base ctor as used, so =
it
    didn't get emitted.

            PR c++/102045

    gcc/cp/ChangeLog:

            * call.c (make_base_init_ok): Call make_used.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1z/aggr-base12.C: New test.=
