This is recommit of r256028 with minor fixes in unittests: CodeGen/Mips/eh.ll CodeGen/Mips/insn-zero-size-bb.ll Original commit message: When identifying blocks post-dominated by an unreachable-terminated block in BranchProbabilityInfo, consider only the edge to the normal destination block if the terminator is InvokeInst and let calcInvokeHeuristics() decide edge weights for the InvokeInst. llvm-svn: 256202
