Introduce builtin intrinsic object to share property values between builtin objects (#3490)
Fixed:
 - Global symbol access
 - Array.prototype.values and Array.prototype[Symbol.iterator] must be the same function object

To test the new functionality arguments object Symbol.iterator property is added.

0fd1ed6f27 Add support for new.target (#3469)
Notable changes:
* Extracted the pure JS/builtin and external C method invocations
  into two new methods (`ecma_op_function_call_{simple, external}`).
* Updated parser/scanner to handle "new.target" correctly.
* Added JS test case.

This patch implements the core part of let/const statements. Redeclarations are correctly
detected and separate contexts are correctly created for these statements. Register
optimizations are also emplyed whenever possible.

 - checking the var statements in eval
 - const are treated as lets
 - single statement checks are missing
 - export declarations are exported as vars, let/const export is not supported
