outside of debugger-support mode. Rip out the existing special-case code when parsing expr-identifier. This means that the Lexer needs a LangOptions. Doug and I talked about just adding that as a field of SourceMgr, but decided that it was worth it to preserve the possibility of parsing different dialects in different source files. By design, the lexer doesn't tokenize fundamentally differently in different language modes; it might decide something is invalid, or it might (eventually) use a different token kind for the same consumed text, but we don't want it deciding to consume more or less of the stream per token. Note that SIL mode does make that kind of difference, and that arguably means that various APIs for tokenizing need to take a "is SIL mode" flag, but we're getting away with it because we just don't really care about fidelity of SIL source files. rdar://14899000 Swift SVN r13896
