This phase hoists complex arguments of supercalls and this-calls out of the enclosing class. Example:
class B(y: Int) extends A({ def f(x: Int) = x * x; f(y)})
is translated to
class B(y: Int) extends A(B#B$superArg$1(this.y)) {
private <static> def B$superArg$1(y: Int): Int = {
def f(x: Int): Int = x.*(x); f(y)
}
}
An argument is complex if it contains a method or template definition, a this or a new,
or it contains an identifier which needs a this prefix to be accessed. This is the case
if the identifier has neither a global reference nor a reference to a parameter of the enclosing class.

needsHoist for an implementation. A hoisted argument definition gets the parameters of the class it is hoisted from as method parameters. The definition is installed in the scope enclosing the class, or, if that is a package, it is made a static method of the class itself.

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