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)

remove arch_irn_class_is macro as it hides usages of arch_irn_class_XXX from grep, also remove useless safety checks against classify of Projs returning wrong values

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

[r27285]

[r27195]

Some more cleanup: Put the return type and other specifiers on the same line as the declarator of a function declaration.

- 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

	Node flags and node registers are stored in a generic backend_info struct now
	instead of every part of the backend doing custom (and slow) stuff
