[cfe-dev] [llvm-dev] MLIR for clang

Currently LLVM uses a low level IR for representing programs. Memory
disambiguation does not happen accurately for constructs like
multi-dimensional arrays.  One of the ways we alleviate the same in LLVM
currently is by using multiversioning of the code. By supporting a
mid-level IR like MLIR we intend to keep the access indices of
multidimensional array and do better disambiguation.
