[PATCH] Minor cleanup of const_and_copies stack
* tree-ssa-scopedtables.c (const_and_copies::const_and_copies): Remove
unnecessary constructor. It's now trivial and implemented inside...
* tree-ssa-scopedtables.h (const_and_copies): Implement trivial
constructor. Add comments to various methods. Remove unused
private fields.
* tree-ssa-dom.c (pass_dominator::execute): Corresponding changes.
* tree-vrp.c (identify_jump_threads): Likewise.
* tree-ssa-threadedge.c (thread_through_normal_block): Fix minor
indentation issues.
(thread_across_edge): Similarly.
(record_temporary_equivalences_from_stmts_at_dest): Remove unused
arguments in constructor call.
