[Bug tree-optimization/36187] [4.3 Regression] Partitioning problem with SFTs (again)

We don't properly mark all fields of the union as base_for_components.  But
the real problem is probably that field-sensitive PTA doesn't consider
structs with unions but we still create SFTs for them.  If we didn't do that
the problem with base_for_components would be avoided as well.
