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.
