llvm-project/flang/test/Lower/Intrinsics/c_f_pointer.f90
Eugene Epshteyn f4e959a0fc [flang][NFC] Converted five tests from old lowering to new lowering (part 54) (#194774) 
Convert five tests to use new HLFIR lowering instead of legacy FIR
lowering:
Lower/Intrinsics/c_f_pointer.f90, Lower/Intrinsics/c_loc.f90,
Lower/default-initialization-globals.f90, Lower/cray-pointer.f90,
Lower/loops.f90
