This reverts commit a63fa62c.

While the inliner could do this right,
the fix for now is to not inline such functions.

Use a special kind of entity on the frame type instead of a value_type
struct inside a method type. This makes replacement of function types
slightly easier (it's still a complex operation though) and handling in
the backend a bit more consistent since it's more or less a normal stack
access (with special offsets).

Also bugfix: The second case used uninitialized memory for the Bad's mode.

Another interface change: gc_irgs() now gets an size_t parameter.
Additionally fixed a memory leak.

[r27271]

- 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]

- cleanup ir_spec generation a bit

[r27251]

We copy over the information for alive nodes so that it is not lost. The
alternative would be deleting it, otherwise the information is wrong as
the indices change.

[r27242]

[r27195]

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

[r27155]

[r27153]

[r27145]

  clumsy. Bring back get_entity_visibility and set_entity_visibility

[r27039]

[r27031]

- 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

[r27030]

Small optimization. Note that the else case crashes libFirm and must be fixed, or disable inlining with exceptions yet.

[r26943]

  an optimization should be decided simply on wether the frontend calls
  it or not.

[r26798]

put optimisation module init function declarations into firm_init.h; make loop inversion and loop peeling available in the public API.

[r26795]

[r26778]

[r26468]

- add more passes

[r26395]

[r26387]

- SymConst's are now ALWAYS placed in the start block
