Merge #6907

6907: Lifetime reference search  r=matklad a=Veykril

PR #6787 but rewritten to make use of the HIR now. This only applies to Lifetimes, not labels. Also Higher-Ranked Trait Bounds aren't supported yet, but I feel like this PR is big enough as is which is why I left them out after noticing I forgot about them.

Supporting renaming required slight changes in the renaming module as lifetime names aren't allowed for anything but lifetimes(and labels) and vice versa for normal names.
