Remove logic avoiding gratuitous incrementing of integer lex dim values in schedule outline creation since these are replaced with {0, 1} in the map simplification step. Further reduce number of lex dims in pairwise maps with the following strategy: once a lex tuple dimension is found where both tuples have non-matching integer values, remove any faster-updating lex dimensions where both tuples have integer values, even if the integers don't match.
