[PATCH] Add support for missed and analysis optimization remarks.

[Quentin Colombet]

Hi Diego,

Thanks for the diff, I was wondering where some of the changes came from :).

This LGTM.

One remark, would it be possible to move the PassRemarkXXX options and related implementation in the DiagnosticInfo implementation too?
I.e., stuff related to static cl::opt<PassRemarksOpt, etc.

If it is possible, you can fix that in a subsequent commit, if it is not I can live with that :).

Thanks,
-Quentin
