        * tree.h (tree_expr_nonzero_p): Export.
        * fold-const.c (tree_expr_nonzero_p): Likewise.
        Return true for CALL_EXPRs that are alloca calls.
        (fold_binary): Use omit_one_operand when checking EQ_EXPRs or NE_EXPRs
        against zero.
        * tree-flow.h (expr_computes_nonzero): Remove.
        * tree-vrp.c (expr_computes_nonzero): Remove.
        (vrp_expr_computes_nonzero): Use tree_expr_nonzero_p.
        (extract_range_from_unary_expr): Likewise.
        * tree-ssa-dom.c (record_equivalences_from_stmt): Use
        tree_expr_nonzero_p.
