Nikita Popov d727505e40 [SimplifyCFG] Remove one-use limitation in FoldCondBranchOnPHI() 
BlockIsSimpleEnoughToThreadThrough() already checks that the phi
(and all other instructions) are not used outside the block, so
this one-use check is not necessary for legality. I also don't
see any reason why it would be necessary for profitability (in
fact, those extra uses will be replaced with constants, which
should be generally profitable).
