Update Clang for rebase to r212749.
This also fixes a small issue with arm_neon.h not being generated always.
Includes a cherry-pick of:
r213450 - fixes mac-specific header issue
r213126 - removes a default -Bsymbolic on Android

+When specified on a function or Objective-C method, the ``carries_dependency``
attribute means that the return value carries a dependency out of the function,
so that the implementation need not constrain ordering upon return from that
function. Implementations of the function and its caller may choose to preserve
dependencies instead of emitting memory ordering instructions such as fences.

+The ``optnone`` attribute suppresses essentially all optimizations
+on a function or method, regardless of the optimization level applied to
+the compilation unit as a whole. This is particularly useful when you
+need to debug a particular function, but it is infeasible to build the

+In Clang, ``__declspec(thread)`` is generally equivalent in functionality to the
+GNU ``__thread`` keyword. The variable must not have a destructor and must have
+a constant initializer, if any. The attribute only applies to variables
+declared with static storage duration, such as globals, class static data
+members, and static locals.
