Philip Reames bcb4c00b78 [GVN] PRE of unordered loads
Again, fairly simple.  Only change is ensuring that we actually copy the property of the load correctly.  The aliasing legality constraints were already handled by the FRE patches.  There's nothing special about unorder atomics from the perspective of the PRE algorithm itself.
