<summary>Changes</summary>
Previously we were less specific for POINTER/TARGET: encoding that they could alias with (almost) anything.
In the new system, the "target data" tree is now a sibling of the other trees (e.g. "global data"). POITNTER variables go at the root of the "target data" tree, whereas TARGET variables get their own nodes under that tree. For example,
```
integer, pointer :: ip
real, pointer :: rp
integer, target :: it
integer, target :: it2(:)
real, target :: rt
integer :: i
real :: r
```
- `ip` and `rp` may alias with any variable except `i` and `r`.
- `it`, `it2`, and `rt` may alias only with `ip` or `rp`.
- `i` and `r` cannot alias with any other variable.
I haven't implemented it in this patch, but I wonder whether it is ever possible for `ip` to alias with `rt` or even `it2`.
While I was updating the tests I fixed up some tests that still assumed that local alloc tbaa wasn't the default.
I found no functional regressions in the gfortran test suite, fujitsu test suite, spec2017, or a selection of HPC apps we test internally.
