- reorganized most instructions to have _i and normal forms
- added support for shift-operand and condition
- removed unused double fp opcodes, use mode instead (not working yet)
- new constant create algorithm creates shorter sequences
- dumper now writes immediate operands

generates add/sub esp

add comments for the supported command line options

removed two extra opcode number at start end end
generates get_<arch>_irn_opcode()
generates #ifdefs's around header file
calls <arch>_register_additional_opcodes only if $additional_opcodes is set

more comments added

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 :-)
