LGTM, although `CHECK`s in the tests to confirm that e.g. the first involves a scavenged register and `s_add`, and the second involves the stack pointer and `s_mov`, and that this happens at the expected offset might make it easier to read and more likely to catch something that breaks this in the future. Right now it isn't clear why there are two nearly identical tests.
