memops are nodes that have memory inputs, you can generically query them
for their memory input. We can also get rid of get_fragile_op_mem in
favor of get_memop_mem.

- The pns of X_regular and X_except are annotated in the opcode now.
- The memory input is annotated in the opcode now
- only nodes with X_regular, X_except are marked fragile

add unknown_jump opflag for the special case of a jump where we can't directly influence the destination and can't predict/change them

libFirm can now be build as static and as dynamic library.
Two defines control it:
FIRM_BUILD must be set when libFirm is build.
FIRM_DLL must be set if libFirm is build as a dynamic library.

The old FIRM_DLL macro is now renamed to FIRM_API.

Additionally

- FIRM_API is added to the ADT headers, this is at least needed for edgfe.
- some more missing FIRM_API's added ...
- add a resource file to show libFirm's version under windows

[r27575]

properly mark symbols in the public API to be exported. This allows us to use -fvisibility=hidden on ELF systems and dllexport on windows

- 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]

CSE neutral to its users, i.e. op(..., x, ...) ~ op(..., y, ...) if x and y are both neutral.
Setting this property to ia32_ProduceVal nodes allow to CSE nodes that differ in ProduceVals only (which themself NEVER are cse'd).
This "fixes" divmod.

- 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

[r26407]

  (We have a separate get_input, and get_output callback for now).
  This should make the code faster for now and is a first step towards
  changing the interface to query register constraints on the mode_T node
  itself instead of the Proj nodes.
- Handle middleend node constraints and stuff in benode.c instead of in each
  backend
- Remove irn_class_branch we already had is_cfop in the middleend
- Fix a bunch of bugs/problems in the process

 - add new operations computed_value_Proj() and equivalent_node_Proj()
 - computed_value_func() uses now const ir_node *
 - removed some old code

[r20950]

- add some doxygen comments
- add the hash irop operation

- simplified be_node_classify()

[r19711]

[r17143]

- renamed op_pin_state field to pin_state (was probaly refactored wrong)
- improved doxygen comments
