- Introduced be_Start which is now used instead of iro_Start+be_RegParams
- further cleanups and fixes along the way

[r26549]

	* benodes store the out register requirements in backend_info now
	  (this is work towards killing the register_requirement callbacks)
	* ir_graph has a pointer to beirg now
	* Other cleanups

- fixed pass number

[r26397]

- add more passes

[r26395]

[r26385]

[r26384]

Remove the pointless function firm_init_hooks(). Its only purpose seems to be to generate a warning on 64bit architectures.

[r26382]

[r26376]

[r26375]

- add an irg_verify_pass()

[r26374]

[r26367]

- add more passes

[r26366]

- more passes implemented
- small fixes

[r26356]

- add more passes

[r26350]

[r26348]

[r26347]

- implemented a pass manager, so optimizations could be added in advance to "a pass" and run an once as a pipeline
- two managers yet: graph manager runs passes on all graphs of an irp, prog manager runs passes on all irp's (currently only one)

- SymConst's are now ALWAYS placed in the start block

[r26236]

[r26222]

[r26190]

Bad nodes just like on Block nodes.
This simplifies get_irn_irg() and implements the idea the the irg can
be retrieved from "the block" of a node.

[r26188]

[r26181]

[r26180]

[r26164]

verify that Projs are in the same Block as their predecessors (and fix bugs in firm where this wasn't the case)
