Bug description:DateTime:setDate() date not used after modify("last day of...")

Description:
------------
When modifying a DateTime object with modify("last day of last month")
syntax and 
followed by a setDate(), the date portion of setDate() is ignored. It
modifies the 
year and the month, but continues to set the day portion to the last day of
the 
month.

If modify() is called with the absolute date instead of setDate(), it
correctly 
sets the date.

Test script:
---------------
<?php
$date = new DateTime('2012-03-30');

$date->modify("last day of last month");
var_dump($date->format('Y-m-d')); // correctly last day of Feb

$date->setDate(2012, 1, 30);
var_dump($date->format('Y-m-d')); // incorrect date

$date->modify('2012-01-30');
var_dump($date->format('Y-m-d')); // does set correct date


Expected result:
----------------
string(10) "2012-02-29"
string(10) "2012-01-30"
string(10) "2012-01-30"

Actual result:
--------------
string(10) "2012-02-29"
string(10) "2012-01-31"
string(10) "2012-01-30"
