Variable templates: handle instantiation of static data member templates
appropriately, especially when they appear within class templates.

Mark variable template implementation as complete. Nearly all of the credit
here goes to Larisse Voufo.

Implement N3760, support for the [[deprecated]] attribute.

This motion appears to have consensus in the C++ committee and is
expected to be voted into the C++14 draft tomorrow during the formal
vote.

No extension warning in C++11 as attributes not specified in the
standard using the standard syntax in C++11 have implementation defined
meaning, and we define the meaning proposed for C++14.

There is one bug exposed as we do not warn on a deprecated template
specialization. I've left a FIXME in the test case and will dig into
that next.

Also, I will add a few more exhaustive test cases of the other features
specified for this attribute in a follow-up commit.

Replace -fobjc-default-synthesize-properties with disable-objc-default-synthesize-properties.

We want the modern behavior most of the time, so inverting the option simplifies
the driver and the tests.
