  1. 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#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.
