Previously, the Objective-C heuristic failed to detect
headers which #imported Objective-C system framework(s) and declared C
functions on top them.

This extends the heuristic to look for statements of the form:

and check if "Foo" is one of the known Objective-C system frameworks.

Test Plan: New tests added. Ran tests with:

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