Simplify Bracket::oppBrack as matchBrack

Instead of Bracket::oppBrack having a complicated contract that checks
whether the bracket is of the expected side and also is of the opposite
side from `this`, unless `this` is a pipe (why are there 2 relevant
sidedness values?), Bracket::matchBrack simply checks whether the
bracket is of the expected side.
