            Bug ID: 32352
           Summary: Provide a way for
                    OptimizationRemarkEmitter::allowExtraAnalysis to check
                    if (specific) remarks are enabled
           Product: tools
           Version: trunk

There is already a need for this.  For example WholeProgramDevirt instantiates
a remark just to check its Enabled field to see if remarks are on or not.  This
actually does not work because clang does not use the Enabled field only (opt's
-pass-remarks* do).

Also GlobalISel wants to do something like this and it's currently using a
cl::opt as a work-around.
