Rename ScalarEvolution's getIterationCount to getBackedgeTakenCount,
...
to more accurately describe what it does. Expand its doxygen comment
to describe what the backedge-taken count is and how it differs
from the actual iteration count of the loop. Adjust names and
comments in associated code accordingly.
