sparc: rewrite address mode matching, we now use offsets for load/store nodes and need less special nodes

use operands_are_normalized when permuting Not operations on Xor inputs to avoid commutative normalisation turning it back

[r27947]

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

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