Geoff RomerandJon Ross-Perkins 9d942f4633 Generate parameter pattern-match IR from pattern IR (#4388) 
Also propagate the pattern IR along with the pattern-match IR, and use
it where appropriate.

Strictly speaking, some parts of the pattern-match IR are allocated
eagerly, while traversing the pattern's parse tree, but they still
aren't actually emitted until we traverse the associated pattern insts.
