[SYSTEMML-1507] Improved compilation of rowwise codegen templates This patch makes two small yet effective improvements to the compilation of rowwise codegen templates: 1) Improved opening condition: We now open new row templates for each matrix-colvector binary operations. The final decision on row vs cell templates still is up to the cost-based plan selection but this extended exploration open more opportunities. 2) Reduced number of temporary vector intermediates: We now apply basic memoization on computing the temporary, thread-local memory requirements in order to avoid double counting in complex DAG structures. Note that this patch also includes a fix for size updates in spark spoof instructions and modifies tests for cellwise and outer product templates because the new opening condition now led to a row template on the original expressions.
