Description:
------------
The get_debug_info handler for BreakIterator shows the text as
type instead of the proper type, and leaks memory.

Test script:
---------------
<?php

$it = IntlBreakIterator::createCharacterInstance();
$it->setText('foo');
var_dump($it);


Expected result:
----------------
object(IntlRuleBasedBreakIterator)#1 (3) {
  ["valid"]=>
  bool(true)
  ["text"]=>
  string(3) "foo"
  ["type"]=>
  string(33) "N6icu_5722RuleBasedBreakIteratorE"
}


Actual result:
--------------
object(IntlRuleBasedBreakIterator)#1 (3) {
  ["valid"]=>
  bool(true)
  ["text"]=>
  string(3) "foo"
  ["type"]=>
  string(3) "foo"
}
