    c++: initialized array of vla [PR58646]

    We went into build_vec_init because we're dealing with a VLA, but then
    build_vec_init thought it was safe to just build an INIT_EXPR because t=
he
    outer dimension is constant.  Nope.

            PR c++/58646

    gcc/cp/ChangeLog:

            * init.cc (build_vec_init): Check for vla element type.

    gcc/testsuite/ChangeLog:

            * g++.dg/ext/vla24.C: New test.=
