Auto merge of #44312 - eddyb:static-by-any-other-name, r=alexcrichton

Browse source 
Use rvalue promotion to 'static instead of static items.

Fixes #44240. Among other things, in crates that do a lot of formatting, this could reduce the number of items, although I haven't measured the performance benefits. If there's a codegen slowdown, that should IMO be solved by caching the output of miri, *not* by using `static`.
