Summary: This is necessary for D21771. In order to add the hotness attribute to optimization remarks we need BFI to be available in all passes that emit optimization remarks. However we don't want to pay for computing BFI unless the hotness attribute is requested. This is achieved by making BFI lazy at the very high-level through a new analysis pass -- BFI is not calculated unless requested. I am adding a test to check the laziness under D21771 where the first user of the analysis is added.
