[PATCH] D124383: llvm-reduce: Do not try to delete frame instructions

[Markus Lavin via Phabricator via llvm-commits]

I recall running into this as well. So this patch will make sure that they are never deleted thus improving reduction speed. But wasn't there a chance that the oracle would indicated that both instructions of the pair were to be deleted which could result in a valid reduction? I guess this is fine though and a better solution would be to deal with the frame pairs in a separate reduction pass anyway.
