  Translate our IR (TreeMakers) into actual Scala Trees using the factory methods in MatchCodeGen.

  Translate our IR (TreeMakers) into actual Scala Trees using the factory methods in MatchCodeGen.

  The IR is mostly concerned with sequencing, substitution, and rendering all necessary conditions, mostly agnostic to whether we're in optimized/pure (virtualized) mode.
