- moved code placement and critical edges removement to own files

that new keep-alives could be added because the cf was changed ...
So do NOT delete these new KA ...
This fixes segfault4.c

- clean up

[r17503]

- 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 ...

Treat Start as a forking op in remove_critical edges. This will place a block here if needed (before loops for instance)

fixed/warnings make it possible to build without interprocedural view and enable that mode by default

Cleanup: Remove trailing whitespace, get_irn_n(n, -1) -> get_nodes_block(n), get_irn_op(n) == op_FOO -> is_Foo(n).

Replaced set_irn_n(*, -1, *) and get_irn_n(*, -1) by new get_nodes_block()/set_nodes_block() implementation
caveats:
 - the old outs do not see the anchor node yet
 - the new edges wrongly use get_irn_n(*, -1)
 - the new edges do not realize that the move of a node moves all its Projs
 - the anchor node still must have the -1 input set (due to edges bug...)

[r15135]

ignore Proj nodes in place_floats_early()

[r15116]

Proj's are now automatically in the block of it's predecessor
get_nodes_block() is free of special cases ...

[r15115]

[r15053]

moved the fixpoint iteration of the current node from optimize_graph() to transform_node(), a more logical place

[r15025]

[r15010]

fixed warnings (some of them were actual bugs), leave 1 apparent bug in irgmod.c as I have no idea how the correct line looks like
