-Make TokenID of IdentifierInfo read-only, remove setTokenID().
-There are 2 instances that change the TokenID for GNU libstdc++ 4.2 compatibility.
  To handler those cases introduce a RevertedTokenID bitfield, RevertTokenIDToIdentifier() and hasRevertedTokenIDToIdentifier() methods.
  Store the bitfield in PCH.
