Add functionality to memcpy-perf benchmark

Add delay option to purposely hurt bandwidth
Convert several hardcoded parameters into command-line options (keeping
defaults)
    - start/end sizes
    - number of samples to be collected
    - dummy mode
Add dummy mode, approximate replication of CPU load without hitting
memory. Possibly useful for comparison. Uses L2 instead of memory.
All added command-line options are optional arguments, keeps existing
behavior

Added new calculation in benchmark output that shows time spent doing
the memory operation vs. time spent during the delay (if present)
