Subject: [PATCH] [Subtarget] Follow up to r355167, add another set of curly
 braces to FeatureBitArray initialization to satisfy older versions of clang.

Apparently older versions of clang like 3.6 require an extra set of curly braces around std::array initializations. I'm told the C++ language was changed regarding this by CWG 1270.
