The new and defaultvalue bytecodes currently lack a check to ensure that the class to instantiate is of the right kind.

These changes add checks in both slow and fast path of the interpreter.

  - unit test added
  - mach5 tier 1 (all failures were pre-existing)


Commit messages:
 - Fix tabs and trailing whitespaces
 - Add type checks to new and defaultvalue
