; The FTRUNC ("round**" x86 asm) fold relies on UB in the case of overflow.
; This used to be guarded with an attribute check. That allowed existing
; code to continue working based on its assumptions that float->int
; overflow had saturating behavior.
;
; Now, we expect a front-end to use IR intrinsics if it wants to avoid this
; transform.
