Remat reworked
Address rematerialization pass is reworked. 1. Logging system has been introduced 2. Rematerialization across BB is enabled by default 3. Experimental functionality to remat loads has been added New heuristic has been introduced to cover for cases that arise with moving instructions across different BB. We collect the data flow from each rematerialization target to its origin instructions and determine the cutoff value by the percentage of total rematerialization targets.
