These llvm-test-suite tests are currently disabled, but if one tries to compile them, one gets a crash.
Tests: llvm-test-suite/Fortran/gfortran/regression: pr84784.f90, team_change_1.f90, team_end_1.f90
Crash:
```
$ flang -c -fcoarray llvm-test-suite/Fortran/gfortran/regression/pr84784.f90
warning: Support for multi image Fortran features is still experimental and in development.
flang: llvm-project/llvm/include/llvm/Support/Casting.h:572: decltype(auto) llvm::cast(From *) [To = mif::ChangeTeamOp, From = mlir::Operation]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
