ART: Rename 'final' DCE pass to 'after_bce'

This change renames the 'dead_code_elimination$final' pass of the
OptimizingCompiler to 'dead_code_elimination$after_bce', as the addition
of another DCE pass later in the pipeline will make 'final' an erroneous
qualifier.

Test: test_art_target, test_art_host
