Chris Tate 14694925c7 Bind a class expression's name used only in a shorthand property, and stop keeping local class prototypes alive

- A named function-local class expression whose only reference to its own
  name is a shorthand property (`static wrap() { return { Packed }; }`)
  now gets its name binding. The self-reference check read the shorthand
  name's property symbol, so the class lowered without the binding and the
  property held a placeholder function instead of the class.
- A function-local class's prototype takes its name from the class
  object's interned name instead of a registered copy. The registry kept
  every such prototype alive until the process exited, so evaluating a
  local class repeatedly kept each evaluation's prototype and the method
  state it captures: a program that evaluates a local class 200,000 times
  and prints each instance peaked at 121 MB, and now at 2 MB.
  Reusing a freed object clears its name.
