Do not expand FusedAssignmentExpression by _InlineOptimizeCommand

[tuchida]

This code is compile error same as #328.

import "console.jsx";

class _Main {

    static function fn(a : number) : void {
        a += 2;
        console.log(a);
    }

    static function main(args : string[]) : void {
        _Main.fn(1);
    }
}

Do not expand FusedAssignmentExpression in the same way as AssignmentExpression and IncrementExpression.

Thank you for reporting the issue. Took your test and fixed the problem in a slightly different way.

It is really a pitfall that FusedAssignmentExpression is not a subclass of AssignmentExpression. It might be better to look into other parts of the code if similar problem exists.

Thanks!

That's for sure. Both of AST is Assignment in Rhino and esprima.
