Don't print inlined function ID in --trace-hydrogen

FunctionLiteral has two purposes: it is a unit of compilation, and it is
also an expression.  Its id() is only for the latter purpose, used by
the continuation of the closure, not by the closure itself.

When we inline, we treat the FunctionLiteral as a unit of compilation,
not as an expression, and as such the FunctionLiteral doesn't have any
meaningful ID.  The right thing to do is not to access the ID when
printing the hydrogen expression.

Classes: Add support for arguments in default constructor

This is currently done by generating a default constructor that looks
like this:

  constructor() {
    %DefaultConstructorSuperCall();
  }

The a runtime function implements the logic which is pretty similar to
Runtime_Apply except that it uses the [[Prototype]] of the current
function.
