This fixes crashes in jack, but a general solution is needed: all
rd functions calling optimize_node must do that!

Restructure IR construction!

This was not done earlier, why?

[r6412]

removed all calles form for () headers

[r6411]

[r6410]

bounds, and Unknown nodes are optimized now, so lesser nodes

[r6409]

[r6408]

[r6407]

removed unused fields from union attributes
renamed new_type_pointer_mode() to new_type_pointer(), now always a
mode argument is needed

[r6406]

renamed new_type_pointer_mode() to new_type_pointer(), it's now
always necessary to give a mode when construction a pointer type
renamed type_visited to firm_type_visited and removed from public i/f
removed #if 0 code
