Tobias Grosser fcc3ad5d3c [ScopDetect / ScopInfo] Get statistics for scops without any loop correctly 
Make sure we also counts scops not containing any loops.

Michael Kruse 7fac28fa4f [ScopDetect] Include zero-iteration loops in loop count. 
Loop with zero iteration are, syntactically, loops. They have been
excluded from the loop counter even for the non-profitable counters.
This seems to be unintentially as the sentinel value of '0' minimal
iterations does exclude such loops.

Fix by never considering the iteration count when the sentinel
value of 0 is found.

This makes the recently added NumTotalLoops couter redundant
with NumLoopsOverall, which now is equivalent. Hence, NumTotalLoops
is removed as well.

Note: The test case 'ScopDetect/statistics.ll' effectively does not
check profitability, because -polly-process-unprofitable is passed
to all test cases.

Michael Kruse 5b228bbb12 [ScopDetection] Add stat for total number of loops. 
The total number of loops is useful as a baseline comparing how many
loops have been optimized in different configurations.

Tobias Grosser 65ce9362b8 [ScopDetection] Compute the maximal loop depth correctly 
Before this change, we obtained loop depth numbers that were deeper then the
actual loop depth.
