This should fix strange overly long immediate values emitted in the
assembler sometimes.

Assembler/linker never supported this anyway.

Just state the copyright and the project the files belong to. You can
then find the COPYING file for the whole project.

This is the new way of handling switch-jumps. The node contains a table
which maps (ranges of) input values to proj numbers. Compared to a
Cond-node this results in a clean consecutive sequence of Proj numbers
(no searching for a free number for the default_pn anymore) and allows
factoring multiple cases jumping to the same block in a single Proj
(though we still need the optimisation in cfopt for that).

reworked ia32 condition code handling, remove backend Bound support (really someone should lower it before the backend

- Introduced be_Start which is now used instead of iro_Start+be_RegParams
- further cleanups and fixes along the way

[r26549]

- Add a generic requirements+register+flag dumper to bearch; This avoids all
  backends/benode having their own slightly different dumpers
- Lots of cleanups in the backends along the way

- fully implemented __builtin_(frame|return)_address in the backend

	Node flags and node registers are stored in a generic backend_info struct now
	instead of every part of the backend doing custom (and slow) stuff
