Summary:
It suppresses intended integer overflows that generate hash values or random numbers.  For judging that the intention of integer overflow, it applies a heuristics: checking if traces of issues include a whitelisted words, e.g., "rand" or "seed".

While we would be able to suppress all integer overflows of unsigned integers since they have defined behaviors, we don't want to miss unintended integer overflows, e.g., that on unsigned index value.

-												[inferbo] On-demand heap symbol using path

Summary:
It materializes symbolic values of function parameters on-demand. The on-demand materialization is triggered when finding a value from an abstract memory and joining/widening abstract memories.

Depends on D13294630

Main idea:

* Symbolic values are on-demand-ly generated by a symbol path and its type
* In order to avoid infinite generation of symbolic values, symbol paths are canonicalized by structure types and field names (which means they are abstracted to the same value). For example, in a linked list, a symbolic value `x->next->next` is canonicalized to `x->next` when the structures (`*x` and `*x->next`) have the same structure type and the same field name (`next`).

Changes from the previous code:

* `Symbol.t` does not include `id` and `pname` for distinguishing symbols. Now, all symbols are compared by `path:SymbolPath.partial` and `bound_end`.
* `SymbolTable` is no longer used, which was used for generating symbolic values with new `id`s.

-												[inferbo] Distinguish array declaration and size-setting in trace

Summary:
This diff distinguishes array declaration and size-setting in trace.  For example, when there is an
assume statement on an array size, the array size can be pruned to another value.  In which case, we
want to see "Set array size" in the trace, instead of "Array declaration".

Summary:
These have proved to be too fragile to maintain as they would often break
compilation of user code. They have been off by default for more than a year
now (D7350715).

Removing the include models shows a more accurate picture of what infer results
look like in production. As such, lots of tests have changed, mostly
biabduction but also in inferbo. SIOF was using include-based models too but
now libc++ is better and iostreams are implemented in a way that SIOF
understands (instead of being magical creatures) so nothing changed there.

-												[inferbo] Distinguish array declaration and size-setting in trace

Summary:
This diff distinguishes array declaration and size-setting in trace.  For example, when there is an
assume statement on an array size, the array size can be pruned to another value.  In which case, we
want to see "Set array size" in the trace, instead of "Array declaration".

-												[cost] add model for NSString.string_with_utf8_string_linear and NSString.length

Summary:
As title
Model `NSString` as `JavaString`.
Since `NSArray` does not contain information about its type of element, we do not use associate string with collection as in Java and C++. In Java, String model is implemented using java collection, and for C++, string model is implemented using vector.
So instead, we use existing `JavaString` model.
