sim: Add helper functions that add PCEvents with custom arguments

This changeset adds support for forwarding arguments to the PC
event constructors to following methods:

addKernelFuncEvent
addFuncEvent

Additionally, this changeset adds the following helper method to the
System base class:

addFuncEventOrPanic - Hook a PCEvent to a symbol, panic on failure.

addKernelFuncEventOrPanic - Hook a PCEvent to a kernel symbol, panic
                            on failure.


System implementations have been updated to use the new functionality
where appropriate.
