            Bug ID: 16190
           Summary: C and OCaml interfaces miss ConstantDataSequential in
                    value classifiers
           Product: libraries
           Version: trunk

patch over LLVM-3.2, also correct for 2013-05-31-SVN

llvm-c/Core.h has a family of LLVMIsAXXX functions, which were not updated when
ConstantDataSequential and subclasses were added. Thus, there are no functions
to check for membership in ConstantDataSequential, ConstantDataArray and
ConstantDataVector.

The OCaml interface consequently does not know about these in ValueKind.t, and
thus classify_value fails (with an exception) when asked to classify any value
from a subclass of ConstantDataSequential.

Solution: add the missing functions and cases in classify_value. See attached
patch.
