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

[r26549]

- Add a generic requirements+register+flag dumper to bearch; This avoids all
  backends/benode having their own slightly different dumpers
- Lots of cleanups in the backends along the way

- fully implemented __builtin_(frame|return)_address in the backend

	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

Merge ia32_am_type_t and ia32_am_arity_t, because (type == ia32_am_None) == (arity == ia32_am_arity_none).

- extend backend generator to support custom irop data
- cleanup and streamline transform code in ia32
- Improve handling of AddAM vs. Add used in AM expressions

[r16254]

 - remove pn_code from general ones
 - add attribute types for condcode and copyb
 - more more attributes into constructors

- some cleanups

[r15756]

- Source and Destination address mode are now constructed during the normal
  transform phase and not as a separate phase
- Remove the old ImmOp stuff
- introduce 8, 16bit cmps, tests
- still some nodes miss SourceAM handling, but generally we should be as good/better than the old code, so I'm comitting now

[r15642]

- Cmov and Set can do AddressMode (for the comparison not for the result) now
- Rewrote should_be_same constraint handler and fixed a little bug in it
