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.
