9315299fbc Minimum fixes for Xcode 9.3 build errors
Summary:
Issue fixed: #1141

This is a set of minimum fixes for Xcode 9.3 rather than #1142. Much smaller diffs 😃

The changes here were done by Xcode's FixIt. See also https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html#//apple_ref/doc/uid/TP40004265-SW5.

> Platform Dependencies
>
> OS X uses several data types—NSInteger, NSUInteger,CGFloat, and CFIndex—to provide a consistent means of representing values in 32- and 64-bit environments. In a 32-bit environment, NSInteger and NSUInteger are defined as int and unsigned int, respectively. In 64-bit environments, NSInteger and NSUInteger are defined as long and unsigned long, respectively. To avoid the need to use different printf-style type specifiers depending on the platform, you can use the specifiers shown in Table 3. Note that in some cases you may have to cast the value.

afd2d29eec Add diffing optimization when result is all deletes or inserts
Summary:
In an attempt to best other diffing libraries, I noticed that pure insert/delete diffing results would be almost 5x slower than changes between existing arrays. This is pretty much a benchmarking enhancement, but improves diffing performance by ~5x when the from-array or to-array is empty.

```
// OLD only inserts
avg: 0.007469, min: 0.006998, max: 0.016550, p50: 0.007254, p75: 0.007712, p90: 0.007899, p95: 0.008345, p99: 0.016550
// NEW
avg: 0.001392, min: 0.001256, max: 0.006772, p50: 0.001289, p75: 0.001348, p90: 0.001533, p95: 0.001614, p99: 0.006772
```

```
// OLD only deletes
avg: 0.005821, min: 0.005669, max: 0.006511, p50: 0.005766, p75: 0.005852, p90: 0.006030, p95: 0.006204, p99: 0.006511
// NEW
avg: 0.001184, min: 0.001096, max: 0.001673, p50: 0.001123, p75: 0.001212, p90: 0.001378, p95: 0.001467, p99: 0.001673
```

Note the average time improvements (seconds).

383660a100 Move index collection to static C function
Summary: Should also just be a c function instead of a block. Much simpler design.

d3e49fd789 Move map builder to static C function
Summary: This is much simpler as a static function instead of a block. Also taking an object vs plucking from the array will lend itself to better performance and reusability later.

19d4f9d1f7 Added compatibility header
Summary:
- Added IGListCompatibility.h file, and imported it in the files where we need the target check.
- Ordered the project by type

In "IGListKit.h" we still have the conditional check for `#if TARGET_OS_EMBEDDED || TARGET_OS_SIMULATOR` - Did we want to make a macro or something for this check?

This is the most Obj-C I've ever done... just felt that was a worthy comment.

Closes #364

ad30e53507 Move macOS and diffing files to Common dir
Summary:
Moving files to `Common` dir so changes are more automated with Buck and easier to manage in the long run. Ran `pod install` on test and example targets. Updated buck file to include `Common` so diffing lib still works.

Part of #270
