Prevented Proj nodes which are successors of IA32 nodes of beeing converted to ProjIu, since those nodes are 128bit Vector Projs. Quick Hack.

Do not unconditionally set the unsigned pnc flag, but only for floating point comparisons. This fixes r15142.

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...)

ignore Proj nodes in place_floats_early()

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

Make the deconv optimisation more aggressive (allow more ops, handle convs with multiple users) and (hopefully) more correct (check if a conv is a downconv at more places).
