getFileEntry - Return the FileEntry corresponding to this FileID.
Like getFileID(), this only works for lexers with attached preprocessors.

| void PreprocessorLexer::LexIncludeFilename | ( | Token & | FilenameTok | ) |
After the preprocessor has parsed a #include, lex and (potentially) macro expand the filename.
If the sequence parsed is not lexically legal, emit a diagnostic and return a result EOD token.

popConditionalLevel - Remove an entry off the top of the conditional stack, returning information about it.
If the conditional stack is empty, this returns true and does not fill in the arguments.

True if in raw mode.
Raw mode disables interpretation of tokens and is a far faster mode to lex in than non-raw-mode. This flag:
Note that in raw mode that the PP pointer may be null.
