[`InferBorrowKind`][ibk] type implements `Delegate` and keeps a map that
records for each upvar which mode of borrow was required. The modes of borrow
can be `ByValue` (moved) or `ByRef` (borrowed). For `ByRef` borrows, it can be
`shared`, `shallow`, `unique` or `mut` as defined in the
[`compiler/rustc_middle/src/mir/mod.rs`][mir_mod].
`ImmBorrow`, `UniqueImmBorrow`, `MutBorrow` as defined in the

`Delegate` defines a few different methods (the different callbacks):
**consume** for *move* of a variable, **borrow** for a *borrow* of some kind
