Andy Kaylor c467faf23c [WinEH] Ignore lifetime.end PHI nodes in empty cleanuppads ...

This fixes a bug where a PHI node that is only referenced by a lifetime.end intrinsic in an otherwise empty cleanuppad can cause SimplyCFG to create an SSA violation while removing the empty cleanuppad. Theoretically the same problem can occur with debug intrinsics.
