Avoid exception checks after calls to some run-time functions
We know that some run-time functions won't thrown an exception, so this
patch annotates them with a tricked NoThrowContext* instead of
ExecutionContext*, which allows the masm isel to detect calls to them
and avoid generating the exception handling checks after the call.
