I've checked in a patch to force the C++ front-end to use proper types which
allows us to optimize the simple test.
I would appreciate it if y'all could look at generate-3.4.ii in more detail and
see if there are other opportunities we're missing.
I'm going to leave this bug open until we're sure the optimizer is doing a
better job at the larger testcase.
