Summary:
This diff extended the polynomial domain to include symbols for closure calls.
When the closure symbol is added to the polynomial? Unknown closure is called inside a function
like,
```
foo() {
self->closure_field();
}
```
Thus, the cost of `foo` becomes `|self->flosure_field|`, rather than unknown. (Note that this
semantics is added only for autoreleasepool size at the moment.)
When the symbol is instantiated? `foo` is called with correct closure contexts.
```
goo() {
self->closure_field = ^(){ ... };
foo();
}
```
The summary of `goo` will have instantiated summary of the closure.

Summary: This diff adds a test, in which autoreleasing lambda is written in an object field, then called later. The test is not analyzed precisely because it cannot follow that a lambda value is written to a field of an object as of now.

Summary:
This diff substitutes closure parameter when it is given via variable. For example,
```
x = ^{ ... }
foo(x)
```
this diff substitutes the closure variable `x`,
```
x = ^{ ... }
foo(^{ ... })
```
so that the specialization of `foo` can be done by `CCallSpecializaedWithClosures.process`.

Summary:
This diff add a model of `NSArray.index_of_object_passing_test` in
autoreleasepool size model.
Worst case autorelease cost is "array size x cost of given test function (lambda)".

Summary:
This diff increases autoreleasepool size when
* caller is non-ARC-compiled
* callee is ARC-compiled
* return type is a pointer to objc object
To distinguish non-ARC-/ARC-compiled:
* extended `translation_unit_decl_info` to have a boolean field `is_objc_arc_on`
* then copied it to `ProcAttributes.t` for each procedures.

Summary:
This diff adds a new experimental checker for detecting size of objects in autorelease pool in ObjC. The basic mechanism is almost the same with the previous cost calculation:
* Autorelease pool size is increased at explicit `autorelease` call
* Autorelease pool size is set as zero by the `autoreleasepool` block.
While it only supports the explicit calls as of now, we will extend the checker to handle more cases in the following diffs.
