c++: temporarily restore VEC_INIT_EXPR gimplify [PR103936]
PR103936 demonstrates that some VEC_INIT_EXPR can still survive into
GENERIC; until that's fixed let's put back the handling in cp_gimplify_expr.
PR c++/103936
PR c++/65591
gcc/cp/ChangeLog:
* cp-gimplify.c (cp_gimplify_expr): Restore VEC_INIT_EXPR handling.
gcc/testsuite/ChangeLog:
* g++.dg/init/aggr15.C: New test.
