Summary:
Specialized closure substitution was broken for conditionals:
```
void foo(dispatch_block_t block1){
if (x){
block1(); // not replaced with specialized implementation
}
}
```
The problem was that when substituting function calls, it only used memory state at the exit node, rather than at each program point.
We could solve this by
- reverting the domain change in D24418560 (c47911359a), i.e. collecting all possible mappings conservatively (e.g. switch the domain back to `Map`)
- pass the `invariant_map` for substitutions at each program point.
We go with the second option here.
The closure substitution is still somewhat broken as exemplified by the following example:
```
void foo(dispatch_block_t block1){
dispatch_block_t local_block = block1;
local_block(); // we don't substitute the call here
}
```

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)".
