4 ; 2 invariant loads, 1 for OBJC_SELECTOR_REFERENCES_
5 ; and 1 for objc_msgSend from the GOT
7 ; 2 invariant load (full multiply, both loads should be hoisted.)
9 ; 2 invariant load (full divide, both loads should be hoisted.) 1 additional instruction for a zeroing edx that gets hoisted and then rematerialized.
