Lex: Return "" when HeaderMap::lookupFilename fails
Change getString() to return Optional<StringRef>, and change
lookupFilename() to return an empty string if either one of the prefix
and suffix can't be found.
This is a more robust follow-up to r261461, but it's still not entirely
satisfactory. Ideally we'd report that the header map is corrupt;
perhaps something for a follow-up.
