Otherwise when we visit all libcalls in updateCGAndAnalysisManagerForPass(), the old libcall is dead and doesn't have a node. We treat libcalls conservatively in LazyCallGraph because any function may introduce calls to them out of thin air. It is weird to change the signature of a libcall since introducing calls to the libcall with a different signature may break, but other passes like deadargelim already do it, so let's preserve this behavior for now. Fixes an issue found in D128830. Reviewed By: psamolysov Differential Revision: https://reviews.llvm.org/D132764
