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. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
