  [NVPTX] Handle symbol-relative integer initializers in aggregates (#201220)

A symbol-relative integer applies an offset outside the ptrtoint, e.g.

    @g = addrspace(1) global i8 0
    @s = addrspace(1) global { i64, i64 }
           { i64 add (i64 ptrtoint (ptr addrspace(1) @g to i64), i64 4),
             i64 7 }

I'm not sure this is an important feature, but it's explicitly
implemented and works for scalars; the bug is that it hits
llvm_unreachable if you use it inside an aggregate.

While we're here, we also add support for Sub in addition to Add.
