Details

We scan the native stack for reference now, so as long the value is held on the stack somewhere (or in a register), there is no need for auto temp rooters any more in most circumstances. Note that the application's stack is scanned as well if they are currently application frames on the call stack. Only heap references have to be rooted explicitly.

Igor, if you want to grab this go ahead. I think you are more qualified than me. Otherwise I will get to this in a couple days when the stack scanning patch is in.
The (len, vec) parameterized form is still needed, along with any custom trace (mark) hook rooters.

JSAutoTempIdRooter is not needed in general with the conservative stack scanning, but JSAutoIdArray is still necessary.

JSAutoEnumStateRooter is still needed for now. I hope to avoid it and over-layered object/private enumerator data structures over in bug 480297.

Obsolete with the removal of tracejit.
