[PATCH] D136684: [clang][ASTImporter] Remove use of ParentMapContext.

[Balázs Kéri via Phabricator via cfe-commits]

This is really a NFC-like change but not NFC because it has visible effects of removing some crashes. I could not produce a test that provokes the wrong case (when `getParents` returns an empty list). Is it enough to have no new test here? If we can get a test for the crash it needs more investigation to check if `RecursiveASTVisitor` works correct and probably a fix at other place.
