[llvm-mca] Simplify eventing by adding an onEvent templated method.
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.
