Dan Gohman 3b205175ea Fix SpeculativelyExecuteBB to either speculate all or none of the phis ... present in the bottom of the CFG triangle, as the transformation isn't ever valuable if the branch can't be eliminated. Also, unify some heuristics between SimplifyCFG's multiple if-converters, for consistency. This fixes rdar://10627242. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147630 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-05 23:58:56 +00:00
