Summary:
Take another page from the Incorrectness Logic book and refrain from reporting issues on paths unless we know for sure that this path will be taken.
Previously, we would report on paths that are merely *not impossible*. This goes very far in the other direction, so it's possible we'll want to go back to some sort of middle ground. Or maybe not. See the changes in the tests to get a sense of what we're missing.

Summary:
Problem: PulseDomain.ml is pretty big, and contains lots of small
modules. The Infer build being a bit monolithic at the moment, it is
hard to split all these small modules off without creating some
confusion about which abstraction barries lay where. For instance, it's
fine to use `PulseDomain.ValueHistory` anywhere, but using `PulseDomain`
itself is sometimes bad when one should use `PulseAbductiveDomain`
instead.
Proposal: a poorman's library mechanism based on module aliasing. This
stack of diffs creates new Pulse* modules for all these small, safe to
use modules, together with `PulseBasicInterface.ml`, which aliases these
modules to remove the `Pulse` prefix. At the end of the stack, it will
contain:
```
module AbstractValue = PulseAbstractValue
module Attribute = PulseAttribute
module Attributes = PulseAttribute.Attributes
module CallEvent = PulseCallEvent
module Diagnostic = PulseDiagnostic
module Invalidation = PulseInvalidation
module Trace = PulseTrace
module ValueHistory = PulseValueHistory
```
This "interface" module can be opened in other pulse modules freely.
