Chris Lattner 2ba3b62149 Enable Load PRE. This teaches GVN to push partially redundant loads up the 
CFG when there is exactly one predecessor where the load is not available.
This is designed to not increase code size but still eliminate partially
redundant loads.  This fires 1765 times on 403.gcc even though it doesn't
do critical edge splitting yet (the most common reason for it to fail).
