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)

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

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

[r27974]

[r27953]

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

[r27938]

make if-conversion and archdep optimisations get their information directly from the backend without frontends needing special code to transfer these infos

[r27937]

beflags: transform modifies_flags property into a callback, use default rematerialisation callback in backends where necessary
