Hello,

Hello,

number_of_iterations_in_loop returns number of iterations by 1 higher
than all the remaining functions.  This is a bit confusing, and also
inefficient (since the most common uses of number_of_iterations_in_loop,
the returned number is immediatelly decreased by one).

The patch fixes the problem by replacing this function with two new
ones (number_of_latch_executions and number_of_exit_cond_executions),
whose names are hopefully a bit less ambiguous about what they are
doing.

nice cleanups, thanks again,

Sebastian
