Summary: This patch adds support for the Attributor to emit remarks on behalf of some other pass. The attributor can now optionally take a callback function that returns an OptimizationRemarkEmitter object when given a Function pointer. If this is availible then a remark will be emitted for the corresponding pass name. Depends on D102197 Reviewed By: sstefan1 thegameg Differential Revision: https://reviews.llvm.org/D102444
