The approach taken in this CL is to incrementally move toward the currently-specced version of modules in ES6. The biggest change in this patch is separating the parsing of modules from the parsing of scripts, getting rid of the 'module' keyword and thus disallowing modules-in-scripts as well as modules-in-modules. The syntax supported by import/export declarations has not yet been significantly changed, with the major exception being that import declarations require a string as the 'from' part. Most of the existing tests have been disabled, with a first new test added in cctest/test-parsing.
