* tree-ssa-coalesce.c (struct coalesce_pair): Add new field INDEX.
(num_coalesce_pairs): Move up earlier in file.
(find_coalesce_pair): Initialize the INDEX field for each pair
discovered.
(compare_pairs): No longer sort on the elements in each pair.
Instead break ties with the index of the coalesce pair.
