Not exactly: we still need knowledge of this in //clang// (`isReplaceableGlobalAllocationFunction` was taught that the variant with a `__hot_cold_t` parameter //is// a replaceable global allocation function, without which knowledge this optimization cannot apply). However we do get rid of that from //llvm//, which is a nice cleanup!
