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 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.

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)

eliminate the unnecessary and especially confusing concept of a 'code_generator' an isa-interface is enough

[r27995]

allow backend to specify endianess, rewrite bitfield emitter to handle little and big-endian byte order

backend is responsible for defining what lowering operations need to be performed => so the logical thing is to use a backend callback for performing lowerings

refactoring: set_frame_entity is a special callbacks for users of the advanced spillslot coalescing interface and not a generic bearch callback thingy anymore
