Please add a comment that the `KnownStringCompareFunctions` string should end with a semicolon.

"options" would convey the idea slightly better, imo.

I don't think this code is specific to "names". Maybe `parseStrings`, `parseList` or `parseSemicolonSeparatedList`?

1. s/parse/parsed/
2. Please enclose parseName in backquotes.
3. It's more common to use `ArrayRef` from llvm/ADT/ArrayRef.h to pass a reference to a number of sequential elements.
