(enum tree_dump_index, TDF_*, get_dump_file_name, dump_enabled_p,
dump_initialized_p, dump_begin, dump_end, dump_node, dump_switch_p,
dump_flag_name, dump_file, dump_flags, dump_file_name,

gimple-pretty-print.h is enough. Do not include tree-dump.h,
include timevar.h and dumpfile.h instead.
(struct numbered_tree_d, compare_decls_by_uid,
dump_enumerated_decls_push, dump_enumerated_decls): Move from here ...

Always define REG_DEAD_DEBUGGING, avoid #ifdef code, because it
leads to errors in the code not selected.
(df_note_compute): Do not print_rtl_with_bb here. Fix compilation
bug if REG_DEAD_DEBUGGING is not 0, get_insns is not available here.
