[SYSTEMML-2357] Parfor data partitioning rewrites on hops For correctness of size propagation, SYSTEMML-2340 and SYSTEMML-2356 moved part of the constant propagation from the parser to inter-procedural analysis (IPA). The latter has many advantages as it works in conjunction with repeated rewrites. So far the parfor optimizer used the original statements from the parser to determine partitioning strategies and formats (for reuse). Due to the deferred constant propagation, there were scenarios were the parfor optimizer now missed partitioning opportunities, especially for block partitioning that usually involve complex indexing expressions. We now completely rewrote this partitioning analysis on hops instead of statements, which seamlessly benefits all previous rewrites and constant propagation.
Additional minor improvements include better size propagation for right indexing hops and more efficient data partitioning analysis (avoid program scans for non-matrix data types).
