Please reviewhttp://cr.openjdk.java.net/~aw/8134873/ forhttps://bugs.openjdk.java.net/browse/JDK-8134873
Implements Lexer/Parser support for ECMAScript 6 binary (0b) and octal (0o) literals. I've renamed OCTAL (legacy octal literal, e.g. 0777) to OCTAL_LEGACY and added OCTAL and BINARY_LITERAL token types (the _LITERAL suffix is to disambiguate with TokenKind.BINARY). Thanks, Andreas
