get_backend_irg_list - none of our backends uses it and in the future
                       the backend should drive the compilation and not
                       give hints to a generic driver
reg_class_alignment  - unused

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).

This also means that dependent modules like bedbgout should be
initialized by begnuas.

This was an odd convention from the past, there's no need for it
anymore.

Old version used parameter.

Backends can configure CopyB lowering, so that it's possible to keep
CopyB nodes in a certain size range for special backend-specific
optimizations.  Furthermore, large CopyBs are turned into memcpy calls.

So we are not forced to use the generic be_Spill, be_Reload functions
which don't work correctly with double-width register requirements.
This should really fix sparc float spill/reload this time.

This was done by removing unnecessary options/options that only
allowed marginal tweakings to improve performance while at the same time
making the interface cumbersome.

The callee/caller saved information is not constant accross different
ABI's, so don't make it constant. Instead, all BE that still use beabi
provide a callback now.
This allows to implement support for x64_64/Win32 and is a necessary step
for the combined x86 BE.

remove strange init_once/inited checks from arch_init functions. Calling it twice is invalid (and crashs anyway)
