Removed redundant terminator code

Now that terminators are instrumented even without -bf-every-bb,
ByteFlopCounters's cond_brs and b_blocks fields are no longer
necessary and have been removed.  Similarly,
bf_accumulate_bb_tallies() and bf_assoc_counters_with_func() no longer
take arguments that describe whether a basic blocked ended and if so,
with what type of terminator.
Corrected and improved static report

Fixed a problem with the tally of static integer operations.  Added
tallies of static basic blocks and static total instructions.
