Summary:
`AccessExpression.t` represents array accesses as `ArrayOffset of t * Typ.t * t
list`, i.e. the index is represented by a list of access expressions. This is
not precise enough when indices cannot be represented as such. In fact, in
general any `HilExp.t` can be an array index but this type was an approximation
that was good enough for existing checkers based on HIL.
This diff changes the type of access expressions to be parametric in the type
of array offsets, and uses this to record `HilExp.t` into them when translating
from SIL to HIL.
To accomodate the option of not caring about array offsets
(`include_array_indexes=false`), the type of array offsets is an option type.

Summary:
`AccessExpression.t` and `HilExp.t` are about to become mutually
recursive, this will help distinguish the actual changes from the moving
of code around.
This deletes the file left around in the previous commit to preserve
callers of `AccessExpression`.

Summary: Use AccessExpressions instead of AccessPath in uninit analysis. This will allow us to distinguish between pointers and their dereferences.
