Summary:
Modify the type of `Exp.Sizeof ...` to include the value that the expression
evaluates to according to the compiler, or None if it cannot be known
statically.
Use this information in inferbo.
Mostly unused in the BiAbduction checker for now, although it could be useful
there too.

Summary:
- Bottom-lift abstract memory domain to express unreachable node
- Two cases to make a node unreachable
+ constant: when an evaluation result of condition expression is
bottom or false, e.g., "prune(0)".
+ alias: when the same structure e is compared to itself with "<",
">", and "!=", e.g., "prune(e < e)".
- Add test for the new prune (prune_constant.c, prune_alias.c)
- Debug the semantics of comparison
