Yes, the set of RuntimeLibcalls should be consistent through a module, and only invalidated on link

Separately I am going to introduce a new LibcallLoweringInfo, which will need to become another analysis which will be function level (though it's really Module + subtarget, so I'm questioning if it should really be a function analysis as well)
