[PATCH] Add an IsLiteral parameter to SpecialCaseList (Clang side).

[Alexey Samsonov]

See my comment in review thread for D4547. I'm not happy with code structure you propose. In particular, I don't see why Clang (?) should know whether DFSan expects to see special case lists in "literal" mode. It's really a DFSan implementation detail, which probably shouldn't be exposed.
