It might be in some cases... maybe? I mean, it might be easier to
analyze in ComputeMaskedBits or something, but we don't really do much
to optimize selects involving zero.

[RFC] Canonicalization of unsigned subtraction with saturation
Hi,
This message is a result of a discussion of backend optimization for sub(max) pattern(https://reviews.llvm.org/D25987), which can be either converted to unsigned min-max or unsigned saturation instruction(if the target supports it).
Currently these versions of the code produce different IR(and we need to manage both types in backend):
