C++2a via http://wg21.link/p0355 permits the library literals of 'd' and 'y'. This patch enables them in the Lexer so that they can be properly parsed. Note that 'd' gets confused with the hex character, so modifications to how octal, binary, and decimal numbers are parsed were required. Since this is simply making previously invalid code legal, this should be fine. Hex still greedily parses the 'd' as a hexit, since it would a: violate [lex.ext]p1 b: break existing code.
