Description:
------------
If parent::<method-name> (NOTE: this is *not* a static invocation) is called in a child class, and <method-name> does not exist in the parent, the parent's __call() magic method is provided the method name (the $name argument) in lower case.

See the code provided to reproduce the problem. The $b->getFoo(); call should output the method name as "getFoo", including the upercase "F" character. Instead, the method name is converted to all lower case. To be consistent with the results of $a->getFoo();, the method name should not be converted to lower case.

This issue is probably related to the recently resolved bug # 42937.

Reproduce code:
---------------
class A
{
  function __call($name, $args)
  {
    echo("magic method called: $name\n");
  }
}

class B extends A
{
  function getFoo()
  {
    parent::getFoo();
  }
}

$a = new A();
$a->getFoo();

$b = new B();
$b->getFoo();

Expected result:
----------------
magic method called: getFoo
magic method called: getFoo 

Actual result:
--------------
magic method called: getFoo
magic method called: getfoo
