; Test that we can replace "scalar" FP-bitwise-logic with the optimal instruction.
; Scalar x86 FP-logic instructions only exist in your imagination and/or the bowels
; of compilers, but float and double variants of FP-logic instructions are reality
; and float may be a shorter instruction depending on which flavor of vector ISA
; you have...so just prefer float all the time, ok? Yay, x86!
