One workaround in this case is to run another forwprop / dce between inlining
and the first alias pass. This get's rid of a lot of pointers and pointed
to temporaries. Still that doesn't address the fundamental problems here.
(but it makes the testcase work nicely within a bound of 600MB peak
memory usage)
