hipe_ppc: Add code rewrite RA callbacks
These will not only be useful for hipe_regalloc_prepass, but also, after
the introduction of a mk_move/2 (or similar) callback, for the purpose
of range splitting.
Since the substitution needed to case over all the instructions, a new
module, hipe_ppc_subst, was introduced to the ppc backend.
