fixed copy inserter bug
changed debugging stuff

omit copy if in==out

fixed the assert and put the whole assert code into #ifdef NDEBUG

Fixed construction of spill-slots and frame type. Aligment was not taken into account (alignment might be bigger than size!)

be_get_empty() checks now that the set is really empty :-)
some comments added

FIRM_DBG_REGISTER() with decl must been the last decl
removed asserts that the empty set is empty. This is now checked in be_get_empty()

be_node_classify() should classify be_Return as a branch. This might be useless
as be_Return consume all register and should be last anyway, but it happen that
keep'ed nodes otherwise are scheduled after Return ...

be_get_IncSP_pred() added

more docu added

to calculate the spill slot size and alignment

arch_register_class_mode() added to retrieve the largest register mode
