* haifa-sched.c (is_cfg_nonregular): Change return type to
an int. No longer compute "estimated" number of edges. Use
computed_jump_p instead of duplicating the code. Fixup/add
some comments.
(build_control_flow): Returns a value indicating an irregularity
in the cfg was detected. Count the number of edges in the cfg.
allocate various edge tables.
(find_rgns): No longer look for unreachable blocks.
(schedule_insns): Do not allocate memory for edge tables here.
Free memory for edge tables before returning. Do not perform
cross block scheduling if build_control_flow returns nonzero.
* flow.c (compute_preds_succs): More accurately determine when
a block drops in.
Fixes various compile hangs after haifa cleanup.

* method.c: Include "system.h" to get stdlib.h, stdio.h,
ctype.h, string.h, etc.
(issue_nrepeats): Add default case in enumeration switch.
(check_btype): Likewise.
(process_overload_item): Likewise.
* Makefile.in (method.o): Depend on system.h.

* haifa-sched.c (build_jmp_edges): Delete dead function.
(build_control_flow): Use cfg routines from flow.c
(schedule_insns): Remove debugging code accidentally checked
in earlier today.
* basic-block.h: Add external integer list structures, typdefs,
accessor macros and function declarations. Simlarly for
basic block pred/succ support and simple bitmap stuff.
* flow.c: Add functions for integer list, basic block pred/succ
support and simple bitmap support.
(compute_dominators): New function to compute dominators and
post dominators.
(find_basic_blocks): Split into two functions.
(life_analysis): Likewise.
(flow_analysis): Removed. Now handled by calling find_basic_blocks,
the life_analysis from toplev.c
* toplev.c (rest_of_compilation): Call find_basic_blocks, then
life_analysis instead of flow_analysis.
