rossberg@chromium.org 83d9e6e7ee Add support for explicit octal and binary integer literals
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-7.8.3

ES6 extends the numeric literals to support explicit support
for binary and octal literals using the following syntax:

  0b10101
  0o777

This is currently behind the flag, --harmony-numeric-literals

BUG=2783
