Davide Italiano 0f62eea7ff [LoopUnroll] Don't try to unroll non canonical loops. ... The current Loop Unroll implementation works with loops having a single latch that contains a conditional branch to a block outside the loop (the other successor is, by defition of latch, the header). If this precondition doesn't hold, avoid unrolling the loop as the code is not ready to handle such circumstances.
