Description:
------------
is_callable() and method_exists() may invoke autoloader with 
unnecessary namespace backslash.

\My\MyClass::func() is the same as My\MyClass::func().





Reproduce code:
---------------
function __autoload($name)
{
	echo $name;
}

is_callable('\My\MyClass::func'); // ERROR

is_callable('My\MyClass::func'); // OK

method_exists('\My\MyClass', 'func'); // ERROR

method_exists('My\MyClass', 'func'); // OK

// defined works well:
defined('\My\MyClass::CONST'); // OK

defined('My\MyClass::CONST'); // OK



Expected result:
----------------
My\MyClass
My\MyClass

My\MyClass
My\MyClass

My\MyClass
My\MyClass

Actual result:
--------------
\My\MyClass
My\MyClass

\My\MyClass
My\MyClass

My\MyClass
My\MyClass
