Patch, 2nd try

Here's take 2. A few test cases also needed fixing.

BTW, the dumps are also ugly because the alias dumper doesn't honor
TDF_DETAILS. If I ask for just the -fdump-tree-pre dump, I get the function
_and_ all the alias analysis constraints and solutions. It would be nice if
that can be fixed as well.
