Rig TransitiveAddressWalker to keep track of enough information for passes to
correctly check for pointer escapes and dependence uses. Requires for precise
bail-outs and asserts.
This makes it so that the move address checker is not dependent on starting the
traversal at a base object. I also included verifier checks that the API can
visit all address uses for:
1. project_box.
2. alloc_stack.
3. ref_element_addr.
4. ref_tail_addr.
5. global_addr_inst.
this is because this visitor is now apart of the SIL API definition as being
able to enumerate /all/ addresses derived from a specific chosen address value.
This is a refactoring NFCI change.
