Fix performance regression introduced in #142531 by excluding `Storage{Live,Dead}` from CGU size estimation



Fix performance regression introduced in rust-lang/rust#142531 ([rust-timer comment](rust-lang/rust#142531 (comment))) by excluding `Storage{Live,Dead}` from CGU size estimation.

Also, avoid unneeded work for storage removal in non-opt builds in CopyProp and GVN
by allocating local sets for the storage accounting only when `tcx.sess.emit_lifetime_markers()`.
