The names "foo", "bar", "baz", "qwe" and "asd" will be mangled, and the
resulting mangled names will be used for the same properties throughout the
code.  The "stuff" will not be, since it's just referenced but never
assigned to.

This *will* break most of the code out there, but could work on carefully
written code: do not use eval, do not define methods or properties by
walking an array of names, etc.  Also, a comprehensive list of exclusions
needs to be passed, to avoid mangling properties that are standard in
JavaScript, DOM, used in external libraries etc.

Add filename to the JS_Parse_Error exception.

It would be nice to have access to the filename of the file that includes the code that causes a JavaScript error. This is especially handy if uglifying multiple files at once.

Only a small change is needed for this to happen as it's already available in the function that throws the error.

The correct format of a sourcemap is acquired
from a mozilla source map generator by calling
toJSON on this object. This patch alters the
toString function on mozilla generators to print
the format that is to spec instead of the generator's
internal representation of itself.
