Module print

Pattern analysis sometimes wants to print patterns as part of a user-visible diagnostic.

Historically it did so by creating a synthetic thir::Pat and printing that, but doing so was making it hard to modify the THIR pattern representation for other purposes.

So this module contains a forked copy of thir::Pat that is used only for diagnostics, and has been partly simplified to remove things that aren’t needed for printing.
