; This test is identical to test64 above with only the destination of the br
; reversed. This somehow causes the two functions to get slightly different
; initial IR. One has an extra invert of the setcc. This previous caused one
; the functions to use a BT while the other used a TEST due to another DAG
; combine messing with an expected canonical form.
