jdoerfert added a parent revision: D73426: [Attributor] Derive memory location attributes (argmemonly, ...).

In addition to a single bit per memory locations, e.g., globals and
arguments, we now collect more information about the actual accesses,
e.g., what instruction caused it, was it a read/write/read+write, and
what the underlying base pointer was. Follow up patches will make
explicit use of this.
