We need the compiler generated variable to override the weak symbol of the same name inside the profile runtime, but using LinkOnceODRLinkage results in weak symbol being emitted in which case the symbol selected by the linker is going to depend on the order of inputs which can be fragile. This change replaces the use of weak definition inside the runtime with a weak alias. We place the compiler generated symbol inside a COMDAT group so dead definition can be garbage collected by the linker. We also disable the use of runtime counter relocation on Darwin since Mach-O doesn't support weak external references, but Darwin already uses a different continous mode that relies on overmapping so runtime counter relocation isn't needed there.
