What exactly are you testing, given that #50699 didn't land yet?

This adds Locks to mono item collection so I want to make sure this doesn't add overhead for single-threaded rustc.

Perf looks mostly unchanged: https://perf.rust-lang.org/compare.html?start=685faa2c3ee062aaf30ddf6d3daf4ef3b576979b&end=e8c5b810fdf5ce9b0078599111416241bb14773b&stat=instructions%3Au.

I got rid of the RefCell which should avoid the performance regression without cfg(parallel_queries). MTRef<'a, MTLock<T> maps to &'a Lock<T> with parallel queries and &'a mut T without.
