; For test:
; 2 invariant loads, 1 for OBJC_SELECTOR_REFERENCES_
; and 1 for objc_msgSend from the GOT
; For test_multi_def:
; 2 invariant load (full multiply, both loads should be hoisted.)
; For test_div_def:
; 2 invariant load (full divide, both loads should be hoisted.) 1 additional instruction for a zeroing edx that gets hoisted and then rematerialized.
