Formatter: Initial support for formatting Objective-C method expressions.
This follows the approach suggested by djasper in PR14911: When a '[' is
seen that's at the start of a line, follows a binary operator, or follows one
of : [ ( return throw, that '[' and its closing ']' are marked as
TT_ObjCMethodExpr and every ':' in that range that isn't part of a ternary
?: is marked as TT_ObjCMethodExpr as well.
Update the layout routines to not output spaces around ':' tokens that are
marked TT_ObjCMethodExpr, and only allow breaking after such tokens, not
before.
Before:
[self adjustButton : closeButton_ ofKind : NSWindowCloseButton];
Now:
[self adjustButton:closeButton_ ofKind:NSWindowCloseButton];
