Auto merge of #81132 - bugadani:map-prealloc, r=matthewjasper
Borrowck: refactor visited map to a bitset This PR refactors `Borrows` and the `precompute_borrows_out_of_scope` function so that this initial phase has a much reduced memory pressure. This is achieved by reducing what is stored on the heap, and also reusing heap memory as much as possible.
