[MachineSink] replace MachineLoop with MachineCycle
MachineCycle can handle irreducible loop. Natural loop
analysis (MachineLoop) can not return correct loop depth if
the loop is irreducible loop. And MachineSink is sensitive
to the loop depth, see MachineSinking::isProfitableToSinkTo().
This patch tries to use MachineCycle so that we can handle
irreducible loop better.
