Fix Work Balance computation in RTS stats
An additional stat is tracked per gc: par_balanced_copied This is the
the number of bytes copied by each gc thread under the balanced lmit,
which is simply (copied_bytes / num_gc_threads). The stat is added to
all the appropriate GC structures, so is visible in the eventlog and in
GHC.Stats.
A note is added explaining how work balance is computed.
Remove some end of line whitespace
Test Plan:
./validate
experiment with the program attached to the ticket
examine code changes carefully
