Replaced RegExp method parser with recursive descent

Browse Source 
Summary:
public

This diff replaces the RegEx module method parser with a handwritten recursive descent parser that's faster and easier to maintain.

The new parser is ~8 times faster when tested on the UIManager.managerChildren() method, and uses ~1/10 as much RAM.

The new parser also supports lightweight generics, and is more tolerant of white space.

(This means that you now can – and should – use types like `NSArray<NSString *> *` for your exported properties and method arguments, instead of `NSStringArray`).
