Adds fake calls to the constructors of local JS classes in calls to
createLocalJSClass.
Given a call of the form
scala.scalajs.runtime.createLocalJSClass(classOf[C], jsClassValue, ???)
this phase fills in the ??? with an array of calls to the constructors
of C, like
[ new C(), new C(???, ???) : Object ]
If the class C has an outer pointer, as determined by the ExplicitOuter
phase, the calls to the constructor insert a reference to the outer
instance:
[ new C(Enclosing.this), new C(Enclosing.this, ???, ???) : Object ]
The LambdaLift phase will further expand those constructor calls with
values for captures. The back-end will extract the values of the outer
pointer and/or the captures to introduce them as JS class captures.
Since we need to insert fake new C() calls, this scheme does not work for
abstract local classes. We therefore reject them as implementation
restriction in PrepJSInterop.
This phase complements ExplicitJSClasses. The latter cannot create the
fake new invocations because that would require inventing sound type
arguments for the class' type parameters in order not to break Ycheck.

Is this phase the standard typerphase? True for FrontEnd, but not for other first phases (such as FromTasty). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).
