Description:
------------
When you type hint with a name of a type PHP has, the error message is ambiguous 
and confusing.

Test script:
---------------
function foo(boolean $bar) {
  var_dump($bar);
}

foo(true);

Expected result:
----------------
Catchable fatal error: Argument 1 passed to foo() must be an instance of the class 
boolean, non-class of type boolean given, called in /code/VhrCdK on line 11 and 
defined in /code/VhrCdK on line 3

This is just my first thoughts on how to make it less confusing. Other suggestions 
would be apperciated.

Actual result:
--------------
Catchable fatal error: Argument 1 passed to foo() must be an instance of boolean, 
boolean given, called in /code/VhrCdK on line 11 and defined in /code/VhrCdK on 
line 3
