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

[r15136]

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()

[r15116]

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).

Adjusted nodesets to it but it is still deactivated.

Removed some old pset_live stuff.

[r15063]

Yeah, it's really long ago since this was touched

[r15062]

I kept the old for benchmarking. As soon as they are done, it will go away.
