rustc_typeck: do not overlap a borrow of TypeckTables with method lookup. If trait selection is reached, it could potentially request a closure signature, which will have to borrow the `TypeckTables` of the current function, and so those tables *should not* be mutably borrowed. Fixes #42463. r? @nikomatsakis
