In the MLIR tests that are testing the translation of LLVM MLIR dialect to LLVM IR, there are tests for argument attributes 

https://github.com/llvm/llvm-project/blob/99e1308c41b24e2422324d68be28e5370196e5d6/mlir/test/Target/LLVMIR/call-argument-attributes.mlir

So usually, it is better to limit flang unit tests to test the steps implemented in flang. However, given there are several steps involved here, and given the MLIR tests to not test sret, it sounds reasonable to add a small integration test from Fortran to LLVM IR.

I added one.
