Jakob Stoklund Olesen 626f3d7a57 Avoid sinking machine instructions into a loop.
MachineLoopInfo is already available when MachineSinking runs, so the check is
free.

There is no test case because it would require a critical edge into a loop, and
CodeGenPrepare splits those. This check is just to be extra careful.
