Cleanup rtmemref api (#238)
* Detect llvm-project commit change in utils/clone-mlir.sh and rebuild llvm-project
for zLinux Jenkins build bot

* Cleanup RtMemRef API

-  use forward declaration to hide private data fields
-  RtMemRef.h: external user header, C/C++
- _RtMemRef.h: internal user header, C++ only
-  RtMemRef.hpp and RtMemRef.cpp: implementation header and file
-  add external APIs
       OrderedRtMemRefDict *ormrd_create(RtMemRef **rmrs, int n)
       RtMemRef **ormrd_getRmrs(OrderedRtMemRefDict *ormrd)
       int ormrd_getNumOfRmrs(OrderedRtMemRefDict *ormrd)
   for creating and querying OrderedRtMemRefDict with RtMemRef arrays
-  data buffer installed by rmr_setData() will be managed by user
-  unique_ptr<RtMemRef> must use custom deleter <RtMemRef,decltype(&rmr_destroy)>
