At this point I am not sure if we should "pollute" the generic MC description with this property, mainly because the ARM backend will be the only user, and it looks like this could be simple target hook switching over the opcodes, like already done in the added unittest. Not pretty, but very simple and effective....
At the same time, there is enough prior art here, adding all sorts of things, so I am in two minds. But I think I would more lean towards a target hook, because it's not very generic/widely used.
Added vminv support

Very nice. Oliver went and put together a few patches for mul, add and sub, in https://reviews.llvm.org/D67268 and related. So we now (or soon will) produce the other instruction this can effect. This is good to go I think.
