Dan Gohman 46bdfb0e6b 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65382 91177308-0d34-0410-b5e6-96231b3b80d8		2009-02-24 18:55:53 +00:00
