Feature request to access source file name

[shibukawa]

I can access to module information by using JSX.require() function from JS code, but there is no way to get primary source file name (it was passed to JSX compiler).

If I can get primary source file name, I can write custom bootstrap code easily.

For example, just import following code, you can export all export classes and use as standard CommonJS code.

native class CommonJSExporter {
} = '''
var module = JSX.require(JSX.getPrimarySourceFile());
for (var key in module)
{
    if (key.match(/^[a-zA-Z0-9]+$/))
    {
        exports[key] = module[key];
    }
}
'''

It can support all styles of entry points. #259 is not needed anymore.

I made a tool that parses resulting JavaScript code and get module information. This is not needed anymore for me.
