Auto merge of #65172 - tanriol:explain_borrow-use-context-dominators, r=nagisa
use precalculated dominators in explain_borrow This looks like the only place calculating dominators from the MIR body every time instead of using the ones stored on the `MirBorrowckCtxt`. For example, in rust-lang/rust#65131 a big generated function with a number of borrowck errors takes a few hours(!) recalculating the dominators while explaining the errors. I don't know enough about this part of rustc codebase to know for sure that this change is correct, but no tests seem to fail as a result of this change in local testing.
