hipe_x86: 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_x86_subst, was introduced to the x86 backend. Due to differences in the 'jtab' field of a #jmp_switch{} between x86 and amd64, it regrettably needed to be duplicated to hipe_amd64_subst.
