        <pre>There currently seems to be no function in the LLVM-C interface which returns a
ConstantAggregateZero value, such as would be used in constructing IR
equivalent to "@a = global [42 x i32] zeroinitializer" or the like.

Something like the following in lib/IR/Core.cpp ought to suffice:

LLVMValueRef LLVMConstAggregateZero(LLVMTypeRef Ty)
{
    return wrap(ConstantAggregateZero::get(unwrap(Ty)));
}</pre>
