Yes, and what I'm saying that TTI should handle this since this is
target-specific lowering.
If you don't want to propagate TLI, then just copy the legality checks from TLI
to TTI and the cost estimation for this specific lowering to the
getArithmeticInstructionCost function. This is what we usually do in similar
cases for other targets.
