Introduce a new code-completion point prior to an identifier in the

selector of an Objective-C method declaration, e.g., given

  - (int)first:(int)x second:(int)y;

this code completion point triggers at the location of "second". It
will provide completions that fill out the method declaration for any
known method, anywhere in the translation unit.
