Remove duplicate DFS walks from DF init
The following removes unused CFG order computes from
rest_of_handle_df_initialize. The CFG orders are computed from df_analyze ().
This also removes code duplication that would have to be kept in sync.
* df-core.cc (rest_of_handle_df_initialize): Remove
computation of df->postorder, df->postorder_inverted and
df->n_blocks.
