checking the specifics of how the function is called shouldn't be in this test
that tests the pipeline, the point of this test is just a quick end-to-end test
testing we inserted instrumentation. if we want to test this we should have a
separate test focused on the exact instruction sequence. but I don't think we
need to add that test coverage in this PR
so I'd remove the `%rdi` CHECK line
