Provide configurable constructor call normalization

Three modes:

- 'disable' (default): normalize constructor calls in coroutines only
  (required because uninitialized objects can't be stored in fields),
  don't insert additional code for forced class initialization;

- 'enable': normalize constructor calls,
  don't insert additional code for forced class initialization;

- 'preserve-class-initialization': normalize constructor calls,
  insert additional code for forced class initialization.
