*	BranchProb: modify the definition of an edge in BranchProbabilityInfo to handle	Manman Ren	2012-08-24	1	-0/+32
	the case of multiple edges from one block to another. A simple example is a switch statement with multiple values to the same destination. The definition of an edge is modified from a pair of blocks to a pair of PredBlock and an index into the successors. Also set the weight correctly when building SelectionDAG from LLVM IR, especially when converting a Switch. IntegersSubsetMapping is updated to calculate the weight for each cluster. llvm-svn: 162572
