- collect_phiprojs() collects all partBlocks of an MacroBlock
- partBlock() now handles MacroBlocks better: the lower part of teh splittet block forms a new MacroBlock
- links should now be free even during construction ...

small functions that should be inlined in libFirm are implemented in _t.h files
with a __ prefix.
Preprocessor magic is used to automatically inline these functions whenever a _t.h
file is included instead of a .h file.
Note that this magic did not work outside libFirm without accessing _t.h files.

Fixed error in backedge: backedge array was not updated
when in array was changed.

  backedges (ana/backedge.h) and to represent loops
  (ana/irloop.h).  The scc algorithm (ana/irscc.c) builds
  both datastructures.
  The algorithm does not yet work properly for interprocedural
  graphs.  Finds more loops than only recursions.
