[PATCH] D49671: [SchedModel] Propagate read advance cycles to implicit operands outside instruction descriptor

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa updated this revision to Diff 159480.
jonpa added a comment.

Patch somewhat simplified with NFC on SystemZ/SPEC. SystemZ test case fixed to use '-o -', to not write the .s file to the repo.

Is this approach acceptable, or are the extra RegAlloc super-reg operands somehow under review / redesign?
