Auto merge of #15549 - Veykril:unwind-if-cancelled, r=Veykril

Add a few more `db.unwind_if_cancelled()` calls

Judging from a profile sent by a friend, the borrowck query took up a significant amount of time in their project which might be the cause for some unresponsiveness as nothing in the mir stack currently unwinds on cancellation
