Summary:
`ModeledRange` represents how many times the interval value can be updated by modeled functions. This
domain is to support the case where there are mismatches between value of a control variable and
actual number of loop iterations. For example,
```
while((c = file_channel.read(buf)) != -1) { ... }
```
the loop will iterates as the file size, but the control variable `c` does not have that value. In
these cases, it assigns a symbolic value of the file size to the modeled range of `c`, then which
is used when calculating the overall cost.

Summary: Before this diff, the analysis would only lookup the attributes with the classname appearing in the instruction. However, it would fail to find those attributes for inherited and not overridden methods. With this diff, the attributes are now searched recursively in the super classes.

Summary:
Preparing for the future change, we won't see instructions as lists but as an abstract type.
This change may be a very minor perf regression: does a few more (but bounded by a constant) instructions traversals only for the nodes involving a Printf-like function call, only for the PrintfArgs checker...

This simplifies the frontends and backends in most cases. Before this diff,

Summary:
Was trying to decide where to add a new Java utility function and realized that things are a bit disorganized.
Some operations on `Typ.Name.t`'s live in `Typ.Procname`, and some live inside an inner `Java` module whereas some are outside of the module with a `java_` prefix.
Let's move toward putting all Java/C/Objc/C++-specific functions in dedicated modules.
This diff does some of the work for Java.
There are Java-specific functions that operate on `Typ.Procname.t`'s that will have to be converted to work on `Typ.Procname.Java.t`'s, but changing those clients will be more involved.
Will also move C/Objc/C++ functions in a follow-up.

Summary:
Found the dead code with the script in the next commit, iteratively until no
warnings remained.
Methodology:
1. I kept pretty-printers for values, which can be useful to use from infer's REPL (or
when printf-debugging infer in general)
2. I kept functions that formed some consistent API (but not often, so YMMV), for instance if it looked like `Set.S`, or if it provides utility functions for stuff in development (mostly the procname dispatcher functions)
3. I tried not to lose comments associated with values no longer exported: if the value is commented in the .mli and not the .ml, I moved the comment
4. Some comments needed updating (not claiming I caught all of those)
5. Sometimes I rewrote the comments a bit when I noticed mis-attached comments
