<pre>I noticed that ARM does not implement the `ARMISelLowering::hasAndNot` function
even though it has the bic / vbic operations[1]. Unfortunately in my tries it's
not as easy as just implementing the function since it leads to changed
patterns for integer saturations which requires updates to codegen matching.
