Summary:
In LLDB, if a method consists only of a single return statement, and you put a breakpoint on that return statement, then when you're stopped at that breakpoint all method arguments appear to be nil.

Steps to Reproduce:
- (BOOL)testFoo:(NSString *)foo {
  return YES; // Put a breakpoint here, run `po foo`. Note that it's nil, even when you passed something else.
}

Expected Results:
You can see the value of foo that was passed to the method

Actual Results:
You can't. It's nil. If you put a breakpoint on the closing brace of the method, then it works. But not on the return statement.

Regression:
Not sure.
