This also means that dependent modules like bedbgout should be
initialized by begnuas.

So we are not forced to use the generic be_Spill, be_Reload functions
which don't work correctly with double-width register requirements.
This should really fix sparc float spill/reload this time.

If req2 was limited and req1 wasn't, then it incorrectly returned true.

This tries to get the names in a consistent format. We basically have 2
views on register allocation/constraints now:

1) Register Requirements and Assigments are per-instruction. Each
   instruction has requirements on its inputs and outputs, register get
   assigned for outputs of an instruction (assignment is an attribute of
   an instruction, not of the Proj-nodes).
   The internal datastructures model this form!

   The functions here have the form:
     arch_get_irn_register_req_in(node, input_nr)
     arch_get_irn_register_in(node, input_nr)
     arch_get_irn_register_req_out(node, output_nr)
     arch_set_irn_register_out(node, output_nr, register)

2) Register Requirements and Assignments are on firm-values. This view
   allows to query/assign requirements and registers at the Proj nodes
   instead of the repsective predecessors.
   This is a convenience interface modeled on top of the other!

   The functions have the form:
     arch_get_irn_register_req(node)
     arch_get_irn_register(node)
     arch_set_irn_register(node, register)

The callee/caller saved information is not constant accross different
ABI's, so don't make it constant. Instead, all BE that still use beabi
provide a callback now.
This allows to implement support for x64_64/Win32 and is a necessary step
for the combined x86 BE.

Only makes it hard to search for arch_register_type_* flags.

eliminate the unnecessary and especially confusing concept of a 'code_generator' an isa-interface is enough

backend: created a (not so nice) macro to iterate over all values defined by an instruction. This avoids lots of small-scale code duplication in the spillers and the prefallocator

refactoring: set_frame_entity is a special callbacks for users of the advanced spillslot coalescing interface and not a generic bearch callback thingy anymore

remove the (mis-)feature of arch_get_irn_reg_req_out working on mode_T nodes and retruning no_reqs in this case

[r27648]

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

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

[r27155]

- 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

[r26542]

	* 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
