Find all references crash on literal with base constraint contextual type

[DanielRosenwasser]

Currently, the crawler/fuzzer has been stuck on TS 20220405 because our single test case crashes on a find-all-references request in dtslint on the string literal "package.json".

https://github.com/microsoft/dtslint/blob/1ccb5736f1e99a81db56df8b59625fd64d8bc061/src/checks.ts#L13

The regression was introduced by #48566, and we would have been able to catch it if we had noUncheckedIndexedAccess.

I'm sure there's a more realistic repro that is actually a problem for users directly, but here's something minimal.

const lol: string = "rofl/**/";

The : string HAS to be there to there in this case.

Request find-all-references in the string at /**/
