I eliminated the loop for GEP, since the first index is different enough from the second. If more than two indices ever show up we can reinstate the loop starting at index 1.

I think that's a good idea. The code is much more readable now.

Here the previous index of the register is replaced rather than added. So code like this: ``` %1 = some global address %2 = GEP %1, 2 %3 = GEP %2, 3 ``` will have `%3` initialized at 3 elements inside the global rather then 5. Is that intended? Maybe it would make sense to emit a warning if a situation like `%3` happens? Or to simply add the offset?
Also, do we already have a way to have pointers to structs? `sm6_parser_declare_global()` allows us to declare arrays of scalars, but right now I don't remember anything about structs.
