Summary: This patch eliminates some redundancy in iterating across Listeners for the Instruction and Stall HWEvents, by introducing a template onEvent routine. This change was suggested by @courbet in https://reviews.llvm.org/D48576. I hope that this patch addresses that suggestion appropriately. I do like this change better than what we had previously.
