  Add auto-upgrade support for annotation intrinsics

The llvm.ptr.annotation and llvm.var.annotation intrinsics were changed
since the 11.0 release to add an additional parameter. This patch
auto-upgrades IR containing the four-parameter versions of these
intrinsics, adding a null pointer as the fifth argument.
