  Log Message:
  -----------
  Loop names used in reporting can grow very large

Summary:
The code for generating a name for loops for various reporting scenarios
created a name by serializing the loop into a string.  This may result in
a very large name for a loop containing many blocks.  Use the getName()
function on the loop instead.
