There was a problem hiding this comment.
I believe that the thinking was that this would help catch an issue where we set the Remat flag on an instruction and forget to update this. But the requirement is too strong since this may be called with target independent instructions.
Perhaps we can get both by asserting that the instruction has a size of zero (or at least less than 4) in the default case.
In any case, this unblocks a bot/commit, so LGTM.

If MI is not PPC specific instructions, let base implementation decide if MI is rematerizable.
This can fix failure in #75570 after #75271 .
