Catchret transfers control from a catch funclet to an earlier funclet.

membership onto the CATCHRET SDAG node.

We shifted the MachineBasicBlocks to the end of the MachineFunction in
DFS order. This will not ensure that MachineBasicBlocks which fell
through to one another will remain contiguous. Instead, implement
a stable sort algorithm for iplist.
This partially reverts commit r214150.

Windows EH funclets need to be contiguous. The FuncletLayout pass will
ensure that the funclets are together and begin with a funclet entry MBB.
