remove get_irn_modename, get_irn_modeident from public API. It's unclear why we need an explicit combination of get_irn_mode and get_mode_name

differentiate between Bad and Deleted (because of exchange) nodes, this avoid some invalid memory accesses when trying to get irg from a Bad node

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

[r27285]

[r27277]

- 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

- reduced number of calls
- kicked C99 comment

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

This commit adds the neccessary attributes to each ir_node. It also adds
the initialization code and some prototypes for the graph_pass and some
support functions.

[r27094]

  clumsy. Bring back get_entity_visibility and set_entity_visibility

[r27039]

- Merge stickyness, visibility and variability into ir_linkage
- Add proper support for common symbols, weak symbols and C++ COMDAT stuff
- Mark OO-features type_visibility, peculiarity and allocation as deprecated
  OO feature will be separated from firm core into higher levels in the long run
- Rework, simplify and fix bugs in begnuas.c

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.
