Just a reminder PR for me.
The reason why auto-parallelization has TODO_rebuild_alias is that it generates
a .paral_data_store structure where it stores pointers to new address-taken
variables and passes the address of that structure to the new parallel worker
clone. This makes ESCAPED incomplete and causes followup DCE to delete stores
to .paral_data_store if points-to information (and ESCAPED) is not rebuilt.
A way to amend the ESCAPED solution should be added and autopar should use it.
