838558 - Kill object equality hook

Status: RESOLVED FIXED

Description

[Tom Schuster [:evilpie]]

Because of CPG we can remove at least XPConnect hooks, see bug 812669. We also have some usage of this in ObjectWrapperParent ("CPOWs"), but I am not sure about those. 
I pushed a patch to try that removes it as well, we will see how this goes.

I guess this could go from ff to 7f.

This is dead code now, as both arms end in a return.  (Which means one or the other should be if'd, and the other bit should be unindented, really.)

Thank you guys. I also removed some unnecessary type query in FastOps.cpp. (Thank you compiler :)

I dropped the changes to XPC before check-in.
