David Majnemer 3785891684 [SimplifyCFG] Remove cleanuppads which are empty except for calls to lifetime.end ...

A cleanuppad is not cheap, they turn into many instructions and result
in additional spills and fills.  It is not worth keeping a cleanuppad
around if all it does is hold a lifetime.end instruction.

N.B.  We first try to merge the cleanuppad with another cleanuppad to
avoid dropping the lifetime and debug info markers.
