SimplifyCFG: Use parallel-and and parallel-or mode to consolidate branch conditions Merge consecutive if-regions if they contain identical statements. Both transformations reduce number of branches. The transformation is guarded by a target-hook, and is currently enabled only for +R600, but the correctness has been tested on X86 target using a variety of CPU benchmarks.
