Hi,

here is an update for the Machine Outliner support on ARM targets.
It addresses the comments received on the initial version and is rebased on current trunk. 
Among the modifications needed by this rebase, this patch propose to move the ARM Low Overhead Loops pass before the Outliner and the Constant Island ones, because it requires the function to track the liveness (which is not the case of the outlined ones) and moving the Constant Island at the end seems more appropriate. If it is ok I'll split the patch and propose the move in a different review, but here is the whole thing such that you can test it.

Thanks
