[GlobalISel] Don't combine instructions which are fed by memory instructions.
If we have a memory instruction (e.g. a load), we shouldn't combine it away in
some trivial combine.
It's possible that, say, a call lives between the instructions. This could
modify the value loaded, making the load instructions not safe to fold.
