Summary:
The thread safety domain manipulates access paths that are a variable
followed by a sequence of field or index accesses. Some expressions
from C++ code do not fit that form, such as cases where subtraction of
an offset from a pointer is used to obtain another pointer, whose
fields are then accessed. Previously the analyzer would crash on such
expressions. This diff partially treats them by introducing dummy
variables.

In C++ it may happen that a procedure return 'variable' is an access
path that cannot be translated to Hil. For now just skip these instead
of crashing.

They are expected to occur in C++ code, so don't fail on them. For now
just skip them, although a better treatment of dynamic dispatch may be
needed later.

Summary:
Indexing into a string literal expression would generate a fresh
variable on every application of a transformer. This violated
finiteness of the domain, and caused divergence.

Summary:
We keep track of both `beginPtr` and `endPtr` but the modelling was mostly
about `beginPtr` as some sort of approximation I guess. This shouldn't change
much but will be useful later when doing more iterator stuff.

This will be needed to re-use the functions now in Driver.ml in other contexts

to do a diff-analysis orchestrator that needs to run the capture and analysis
