Jingu Kang 33e60484d7 [MachineLICM] Handle Subloops ...

MachineLICM pass handles inner loops only when outmost loop does not have unique
predecessor. If the loop has preheader and there is loop invariant code, the
invariant code can be hoisted to the preheader in general. This patch makes the
pass handle inner loops in general.
