  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.

    The substitution that specifies the trees that compute the values of the subpattern binders.

    Should not be used to perform actual substitution! Only used to reason symbolically about the values the subpattern binders are bound to. See TreeMakerToCond#updateSubstitution.

    Overridden in PreserveSubPatBinders to pretend it replaces the subpattern binders by subpattern refs (Even though we don't do so anymore -- see scala/bug#5158, scala/bug#5739 and scala/bug#6070.)

    TODO: clean this up, would be nicer to have some higher-level way to compute the binders bound by this tree maker and the symbolic values that correspond to them

   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.
