Thanks for reporting and addressing this issue.
I'm not entirely sure though that the solution should be adding support for unrealized casts in the translator. As we end up with the unrealized type conversion, it seems our type conversion in `MemRefToEmitC` may not cover this case.
I wonder if the solution you propose (generating a cast to a pointer to an array and supporting it in `emitc.subscript`) can be implemented as part of lowering so that we don't get the unrealized cast in the first place?
