* tree-ssanames.c (make_ssa_name_fn): Strengthen assert.
* fold-const.c (fold_comparison): Check for default def first
before checking for PARM_DECL.
* tree-complex.c (get_component_ssa_name): Likewise.
* tree-inline.c (remap_ssa_name): Likewise.
* tree-ssa-loop-ivopts.c (parm_decl_cost): Likewise.
* tree-ssa-structalias.c (get_fi_for_callee): Likewise.
(find_what_p_points_to): Likewise.
* tree-ssa-operands.c (add_stmt_operand): Simplify.
