Hi Dan,
I'm sorry to be such a pain, but this seems like a step backward.

This achieves two things:
1. Just looking at the .td file, you can tell which instructions are
candidates for remat.
2. The isRematerializable predicate is faster for instructions that
are not remat-able.
3. The isReallyRematerializable only needs to be implemented by
targets with

Speed is something to consider, but I don't think it should override

It seems that simple remat works for things that:
1. have no side effects
2. have no register inputs
Is there another condition?
Can't think of any.
If so, simple remat can check #2 today, just by itself looking at the
machineinstr. Given that, it comes down to how we want to

I don't see a better way so I guess this will be a targetinstrinfo

Okay, the tricky thing here is instructions that have conditional
side effects. For example, all instructions marked isload/isstore/
