1495ceac - [flang] Add hlfir.index op to represent index intrinsic function (#157575)

[flang] Add hlfir.index op to represent index intrinsic function (#157575) The change adds a new HLFIR operation. A call to index intrinsic now becomes lowered into the hlfir.index op and then naive lowering of the op translates it back to appropriate runtime call. The change set is aimed to be functionally equivalent to exiting index functionality, but is much more efficient in a case of presence of the 'kind' intrinsic parameter. Also fixed couple of parameter lowering issues which were revealed while working on the index-related functional parts.
