Marcel Koester 0425332015 [mlir] Added new RegionBranchTerminatorOpInterface and adapted uses of hasTrait<ReturnLike>. ... This CL adds a new RegionBranchTerminatorOpInterface to query information about operands that can be passed to successor regions. Similar to the BranchOpInterface, it allows to freely define the involved operands. However, in contrast to the BranchOpInterface, it expects an additional region number to distinguish between various use cases which might require different operands passed to different regions. Moreover, we added new utility functions (namely getMutableRegionBranchSuccessorOperands and getRegionBranchSuccessorOperands) to query (mutable) operand ranges for operations equiped with the ReturnLike trait and/or implementing the newly added interface. This simplifies reasoning about terminators in the scope of the nested regions. We also adjusted the SCF.ConditionOp to benefit from the newly added capabilities.
