Avoid problems of overwriting good type information with incomplete information
when type declaration happens after its complete definition.
The solution is that we will only time we *update* type information is
when struct declaration has definition as well (which should happen once)

The inductive list predicate was not firing during abstraction because of a type mismatch between C and Java. In Java, the second parameter of the `Sil.Sizeof` constructor is always `Sil.Subtype.exact` in C but is `Sil.Subtype.subtypes` in Java. This diff fixes the confution by comparing the `Sil` types only instead of the type expressions.

The analysis of the Buck project was failing because this script converts the aliases into their expanded target names. It turns out that for Buck, the name of the command is `buck` and the name of the alias is also `buck`, which led to conflicts. This is now fixed by only replacing the targets in the part of the command line that is after `build` in `buck build ...`

Java synthetic methods used to be inlined when a procedure was being analyzed.
This was done almost everywhere. A missing case was when a cfg is loaded during an existing analysis because on-demand needs access to a procedure.
Intead of trying to maintain an invariant in all access paths, we now inline them systematically before saving the cfg to disk.
A secondary consequence of this is that in debug mode the cfg dotty file will show the inlined cfg, so there's no difference between that view and what happens during analysis.

This expression is used to value-initialize non-class types. Per definition of value initialization for non-class types:
1. If it's an array, value-initialize each of its elements
2. Otherwise, zero-initialize it

I was unable to reproduce (1) in a way that produced CXXScalarValueInitExpr and so this diff

xvalues is concept introduced in C++11. While they are not same as lvalues, they have one common trait:
They have identity which means that:
> it's possible to determine whether the expression refers to the same entity as another expression, such as by comparing addresses of the objects or the functions they identify (obtained directly or indirectly);
It means that as far as backend is concerned, they should be treated in same way. Right now there is no concept of "move" in the backend and so we don't have
to differentiate between them.

The Worklist module currently encapsulates a global data structure. Likewise for the global variables for the join state and pathset todo and visited.
This diff refactors the Worklist module into an API where instances of the record can be created and passed around. All the global state is included in the record.
The Worklist data structure never escapes the Interproc module.
