<h3>Log Message</h3>
<pre><https://webkit.org/b/125141> Modernize the JavaScriptCore API headers
<rdar://problem/15540121>
This consists of three main changes:
1) Converting the return type of initializer methods to instancetype.
2) Declaring properties rather than getters and setters.
3) Tagging C API methods with information about their memory management semantics.
Changing the declarations from getters and setters to properties also required
updating the headerdoc in a number of places.
