<pre>Currently, llvm-mca complains only if the instruction is marked
as unsupported in the sched model. That isn't ideal, in order to
get it right, one needs to somehow keep track of every instruction,
and mark unsupported as such, via InstRW.
But that info is already there, the llvm knows what instruction
sets are supported by what cpu.
It would be great to simply make use of that info.</pre>
