Functions
static KeywordStatus	getKeywordStatusHelper (const LangOptions &LangOpts, TokenKey Flag)

static KeywordStatus	getKeywordStatus (const LangOptions &LangOpts, unsigned Flags)
	Translates flags as specified in TokenKinds.def into keyword status in the given language standard.

static void	AddKeyword (StringRef Keyword, tok::TokenKind TokenCode, unsigned Flags, const LangOptions &LangOpts, IdentifierTable &Table)
	AddKeyword - This method is used to associate a token ID with specific identifiers because they are language keywords.

static void	AddCXXOperatorKeyword (StringRef Keyword, tok::TokenKind TokenCode, IdentifierTable &Table)
	AddCXXOperatorKeyword - Register a C++ operator keyword alternative representations.

static void	AddObjCKeyword (StringRef Name, tok::ObjCKeywordKind ObjCID, IdentifierTable &Table)
	AddObjCKeyword - Register an Objective-C @keyword like "class" "selector" or "property".

static void	AddNotableIdentifier (StringRef Name, tok::NotableIdentifierKind BTID, IdentifierTable &Table)

static KeywordStatus	getTokenKwStatus (const LangOptions &LangOpts, tok::TokenKind K)
	Checks if the specified token kind represents a keyword in the specified language.

static bool	startsWithWord (StringRef name, StringRef word)
	Interpreting the given string using the normal CamelCase conventions, determine whether the given string starts with the given "word", which is assumed to end in a lowercase letter.
