fortran: Fix up hash table usage in gfc_trans_use_stmts [PR108451]
The first testcase in the PR (which I haven't included in the patch because it is unclear to me if it is supposed to be valid or not) ICEs since extra hash table checking has been added recently. The problem is that gfc_trans_use_stmts does tree *slot = entry->decls->find_slot_with_hash (rent->use_name, hash, INSERT); if (*slot == NULL) and later on doesn't store anything into *slot and continues. Another spot a few lines later correctly clears the slot if it decides not to use the slot, so the following patch does the same. 2023-02-03 Jakub Jelinek <jakub@redhat.com> PR fortran/108451 * trans-decl.cc (gfc_trans_use_stmts): Call clear_slot before doing continue.
