Add a new attribute meta-spelling called "GCC" -- it widens into being a GNU spelling, and a CXX11 spelling with the namespace "gnu". It also sets a bit on the spelling certifying that it is known to GCC. From this, we can warn about the extension appropriately. As a consequence, the FunctionDefinition functionality is completely removed.

Replacing the functionality from r199676, which didn't solve the problem as elegantly.

Temporarily disable test that fails on Mac OS X 10.9.

PR18322. This test will be reenabled when the SDK gets fixed. In the meantime,
it is pretty disruptive to have this test keep failing.

Rumors of test_debuginfo's death are slightly exaggerated.
