Manman Ren 6342812033 BranchProb: modify the definition of an edge in BranchProbabilityInfo to handle ... 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		2012-08-24 18:14:27 +00:00
