the Interpreter class.

Reviewed by Oliver Hunt.

This change is needed to prepare for making Interpreter::getStackTrace()
private. It does not change the behavior of the code, only the lexical
scoping.

* interpreter/Interpreter.h:
- Added helper functions for ErrorConstructor and NativeErrorConstructor.
* runtime/ErrorConstructor.cpp:
(JSC::Interpreter::constructWithErrorConstructor):
(JSC::ErrorConstructor::getConstructData):
(JSC::Interpreter::callErrorConstructor):
(JSC::ErrorConstructor::getCallData):
- Don't want ErrorConstructor to call Interpreter::getStackTrace()
  directly. So, we moved the helper functions into the Interpreter
  class.
* runtime/NativeErrorConstructor.cpp:
(JSC::Interpreter::constructWithNativeErrorConstructor):
(JSC::NativeErrorConstructor::getConstructData):
(JSC::Interpreter::callNativeErrorConstructor):
(JSC::NativeErrorConstructor::getCallData):
- Don't want NativeErrorConstructor to call Interpreter::getStackTrace()
  directly. So, we moved the helper functions into the Interpreter
  class.
