maekawatoshiki 74f0f9a455 [LICM] Create LoopNest Invariant Code Motion (LNICM) pass ...

This patch adds a new pass called LNICM which is a LoopNest version of LICM and a test case to show how LNICM works.
Basically, LNICM only hoists invariants out of loop nest (not a loop) to keep/make perfect loop nest. This enables later optimizations that require perfect loop nest.
