OK - not sure what aarch64 policy is, but x86 we tend to continue support for old intrinsics that could still be in IR through AutoUpgrade.cpp which mostly converts them to generics (very similar to CGBuiltin) - technically we plan to remove the oldest at some point but we've been very loathe to actually do it.
