Fix a bug that crashed clang when parsing this:
...
class C {
static const int number = 50;
static int arr[number];
};
Here's how it worked:
-GetTypeForDeclarator was called from both Sema::ActOnCXXMemberDeclarator and Sema::ActOnDeclarator.
-VariableArrayTypes are not uniqued so two VariableArrayTypes were created with the same DeclRefExpr.
-On exit they both tried to destroy that one DeclRefExpr.
The fix is not to use GetTypeForDeclarator from the Sema::ActOnCXXMemberDeclarator.

Use template to distinguish between function variants.
...
GCC 4.4.0 gives an error on the "int" declaration for example
saying that it has already been declared (using the "short"
one). Using templates here allow the compiler to distinguish
between the function to choose.
Also, "llvm/Support/DataTypes.h" was not included, leading to
error messages about not knowing "uint32_t" for example.
