These compute the average of two given values, rounding up and down, respectively, if the result isn't exact. When possible, these are mapped to target-specific intrinsics (PADD[BW] on IA and VH[R]ADD[US] on NEON.) A subsequent commit will add pattern-matching to generate calls to these intrinsincs when the corresponding patterns are detected in the IR.)
