Summary:
This diff revises the translation of message expression's arguments in ObjC frontend. In the
frontend, it massages the arguments when calling a static method, so the class or object value is
not given to the static method as the first parameter.
The problem is that it used a raise-exception-and-catch way to detect where we remove the first
parameter. This way of using an exception is not only hard to understand, but also incorrectly
removed the first parameter, with breaking abstract semantics sometimes. (See the added test.) This diff
avoids using the exception.

Summary:
As title
Model `NSString` as `JavaString`.
Since `NSArray` does not contain information about its type of element, we do not use associate string with collection as in Java and C++. In Java, String model is implemented using java collection, and for C++, string model is implemented using vector.
So instead, we use existing `JavaString` model.

Summary:
Add objc test case for ```NSInteger``` and ```NSString```.
The test cases are adapted from java test case: ```IntTest.java```, ```StringBuilder.java```, and ```StringTest.java```.
Inspection of the record will be done later.
