Johannes Doerfert 15fa1ae2ef [Attributor][Fix] Initialize the cache prior to using it ...

Summary:
There were segfaults as we modified and iterated the instruction maps in
the cache at the same time. This was happening because we created new
instructions while we populated the cache. This fix changes the order
in which we perform these actions. First, the caches for the whole
module are created, then we start to create abstract attributes.

I don't have a unit test but the LLVM test suite exposes this problem.
