Teach LazyValueInfo that allocas aren't NULL. Over all of llvm-test, this saves half a million non-local queries, each of which would otherwise have triggered a linear scan over a basic block. Also fix a fixme for memory intrinsics which dereference pointers. With this, we prove that a pointer is non-null because it was dereferenced by an intrinsic 112 times in llvm-test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123533 91177308-0d34-0410-b5e6-96231b3b80d8
