The following runtime functions (and their intrinsic counter parts) are completely unused/obsolete by now - %ToInteger - %GeneratorGetInputOrDebugPos and in addition the intrinsics for %_ToNumber and %_IsJSProxy are also dead (according to code coverage and manual verification), so drop them as well (their runtime function counterparts are still somewhat used).
