Perform linear loop transformations on tree. This flag can improve cache
performance and allow further loop optimizations to take place.

+@item -ftree-loop-im
+Perform loop invariant motion on trees. This pass moves only invariants that
would be hard to handle on rtl level (function calls, operations that expand to
nontrivial sequences of insns). With @option{-funswitch-loops} it also moves
operands of conditions that are invariant out of the loop, so that we can use
just trivial invariantness analysis in loop unswitching. The pass also includes
store motion.

Create a canonical counter for number of iterations in the loop for that
determining number of iterations requires complicated analysis. Later
optimizations then may determine the number easily. Useful especially
