Fix bot failure by loosening up the register matching on new test:

// OPT-NOT: call void @llvm.assume
// We should have only one @llvm.assume call, the one that was expanded
// from the builtin in the IR below, not the one fed by the type test.
-// OPT: %cmp = icmp ne %struct.A* %0, null
+// OPT: %cmp = icmp ne %struct.A* %{{.*}}, null
// OPT: void @llvm.assume(i1 %cmp)
// Check after the builtin assume again that we don't have a type test assume
// sequence.
