MFC r261680:
Pull in r200899 from upstream clang trunk:
Allow transformation of VariableArray to ConstantArray.
In the following code:
struct A { static const int sz; };
template<class T> void f() { T arr[A::sz]; }
the array 'arr' is represented as a variable size array in the template.
If 'A::sz' gets value below in the translation unit, the array in
instantiation can turn into constant size array.
This change fixes PR18633.
Differential Revision: http://llvm-reviews.chandlerc.com/D2688
This fixes "Assertion failed: (T::isKind(*this)), function castAs"
errors, which can occur when building the security/quantis port.
