- A `memmove` test seems to be missing ?
- When the tbaa format is in 'new struct path tbaa' (-Xclang -new-struct-path-tbaa)  format, the resulting shuffling should not be valid ? aka, the new struct path tbaa contains offset and size. Offset is likely to be 0 and size should be the size of a single element.
  - Either that should be filtered out,
  - or the size should be adapted,  (But what with about an unknown size ?)
  - or maybe it should be converted into 'struct path tbaa' ?
