Craig Topper 7d3aba6687 [SimplifyCFG] Teach merge conditional stores to handle cases where the PostBB has more than 2 predecessors by inserting a new block for the store. 
Summary:
Currently merge conditional stores can't handle cases where PostBB (the block we need to move the store to) has more than 2 predecessors.

This patch removes that restriction by creating a new block with only the 2 predecessors we care about and an unconditional branch to the original block. This provides a place to put the store.
