compiler: fix few unused_peekable and needless_pass_by_ref_mut clippy lints This fixes few instances of `unused_peekable` and `needless_pass_by_ref_mut`. While i expected to fix more warnings, `needless_pass_by_ref_mut` produced too much for one PR, so i stopped here. Better reviewed commit by commit, as fixes splitted by chunks.
