Duncan P. N. Exon Smith b5ce11fcc6 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. llvm-svn: 261596		2016-02-23 00:48:16 +00:00
