* genmatch.c (capture_info::walk_c_expr): Ignore capture
uses inside TREE_TYPE ().
* gimple-ssa-strength-reduction.c (stmt_cost): Use CASE_CONVERT.
(find_candidates_dom_walker::before_dom_children): Likewise.
(replace_mult_candidate): Use CONVERT_EXPR_CODE_P.
(replace_profitable_candidates): Likewise.
* tree-ssa-dom.c (initialize_hash_element): Canonicalize
CONVERT_EXPR_CODE_P to CONVERT_EXPR.
* convert.c (convert_to_integer): Use CASE_CONVERT.
