[IR] Disallow llvm.global_ctors and llvm.global_dtors of the 2-field form in textual format 

The 3-field form was introduced by D3499 in 2014 and the legacy 2-field
form was planned to be removed in LLVM 4.0

For the textual format, this patch migrates the existing 2-field form to
use the 3-field form and deletes the compatibility code.
test/Verifier/global-ctors-2.ll checks we have a friendly error message.

For bitcode, lib/IR/AutoUpgrade UpgradeGlobalVariables will upgrade the
2-field form (add i8* null as the third field).

parameter is required to be a simple constant. This annotation must
be accurate to avoid possible miscompiles.
* The 2-field form of global variables ``@llvm.global_ctors`` and
``@llvm.global_dtors`` has been deleted. The third field of their element
type is now mandatory. Specify `i8* null` to migrate from the obsoleted
2-field form.
