* dce.c (dce_process_block): Copy into DF_LR_IN.
* df-problems.c (df_lr_free_bb_info): Support bb_info->in
being the same bitmap as bb_info->top.
(df_lr_alloc): The adef and ause fields must be either
both NULL or both non-NULL. Initialize bb_info->top
to bb_info->in.
(df_lr_bb_local_compute): Allocate adef, ause, top together.
(df_lr_transfer_function): Simplify according to above
assumptions.
(df_lr_free): Zero out bb_info->top instead of freeing it
if it is the same as bb_info->in.
