[PATCH] D44632: [clang-format] Add a few more Core Graphics identifiers to ObjC heuristic

[Ben Hamilton via Phabricator via cfe-commits]

benhamilton created this revision.
benhamilton added reviewers: jolesiak, djasper.
Herald added subscribers: cfe-commits, klimek.

We received reports of the Objective-C style guesser getting a false
negative on header files like:

CGSize SizeOfThing(MyThing thing);

This adds more Core Graphics identifiers to the Objective-C style
guesser.

Test Plan: New tests added. Ran tests with:

  % make -j12 FormatTests && ./tools/clang/unittests/Format/FormatTests
