Chris Lattner 08af5a9dad implement support for sinking a load out the bottom of a block that ...

has no stores between the load and the end of block.  This works 
great and sinks hundreds of stores, but we can't turn it on because
machineinstrs don't have volatility information and we don't want to
sink volatile stores :(
