DecodeTrigraphChar - If the specified character is a legal trigraph when prefixed with ??, emit a trigraph warning. If trigraphs are enabled, return the result character. Finally, emit a warning about trigraph use whether trigraphs are enabled or not.

GetMappedTokenLoc - If lexing out of a 'mapped buffer', where we pretend the lexer buffer was all expanded at a single point, perform the mapping. This is currently only used for _Pragma implementation, so it is the slow path of the hot getSourceLocation method. Do not allow it to be inlined.

isBlockCommentEndOfEscapedNewLine - Return true if the specified newline character (either \n or \r) is part of an escaped newline sequence. Issue a diagnostic if so. We know that the newline is inside of a block comment.
