Add flags -Rpass-missed and -Rpass-analysis.
Summary:
These two flags are in the same family as -Rpass, but are used in
different situations.
-Rpass-missed is used by optimizers to inform the user when they tried
to apply an optimization but couldn't (or wouldn't).
-Rpass-analysis is used by optimizers to report analysis results back
to the user (e.g., why the transformation could not be applied).
Depends on D3682.
