The gain from using an extra Unreachable is rather low, plus the noreturn call must probably be keeped anyway, so revrt it again

[r27898]

Unreachable nodes mark unreachable control flow (after noreturn calls). They
"eat" the memory, saving the two keeps used before.

Works mostly yet (scheduler issues warning about not scheduled Unreachable's)

change betranshelp semantic to panic instead of duplicating node in case of missing transformer. Add generic API for setting transformers

invalidate phase info before starting the code selection; temporary disable freeing of old phases in dead code elimination to avoid problems

[r27309]

- rework ir_phase API
(sorry for mixing these 2 things into 1 commit)

[r27285]

- remove a bunch of code which unexpectedly dependent on current_ir_graph being
  set to something
- fix unnecessary double creation of backedge arrays in some cases

[r27265]

[r27153]

- 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

Add be_dep_on_frame() to let a node depend on the frame, so it does not get scheduled before it can be spilled.

Do not mark the node as visited before transforming it.  This is not necessary anymore since Phis put their predecessors in a worklist, so we cannot walk in a circle.

[r22613]

[r22612]

Remove redundant be_set_transformed_node() in transformer functions.  They are vestiges of old transform semantics.  Their caller (transform helper) handles this.
