Introduce a `ptr_provenance` member to MemoryLocation.

Note: in the full restrict patches, the `ptr_provenance` was tracked through the `AAMDNodes`. For this extraction of the feature, I feel that the MemoryLocation is a more logical place for it. (aka, the provenance is associated to a location, not to the Alias Analysis Metadata).
