match: move normalize() call out of matcher constructors

By passing in the result of the normalize() call, we prepare for
moving the special handling of patterns that always match out of the
patternmatcher.

It also lets us remove many of the arguments from the matcher, because
they were passed only the the normalize function (we could have
removed the arguments by binding them to the function instead of
moving the normalize() call out).
