[amanasifkhalid]

Part of #32648. Per this comment, I suspect this is the next (last?) step in removing IL verifier from the importer.

cc @dotnet/jit-contrib -- are there any CI legs worth running for this?

I suspect this is the next (last?) step in removing IL verifier from the importer.

We might want to do some renaming, say verCurrentState -> stackState or something. And there are various comments that could be updated/removed.

I don't think so; no diffs should be sufficient.

Our SPMI collection set is a bit impoverished right now, so maybe wait until that's fixed and rerun?

Sure; I'll get the renaming out of the way in the meantime.
