MatchBranchSimplification: fix equal const bool assignments The match branch simplification is applied when target blocks contain statements that are either equal or perform a const bool assignment with different values to the same place. Previously, when constructing new statements, only statements from a single block had been examined. This lead to a misoptimization when statements are equal because the assign the *same* const bool value to the same place. Fix the issue by examining statements from both blocks when deciding on replacement.
