The operand_alternative cache was LRA's only per-subtarget state
so a lot of this patch is removing the associated initialisation
and target_globals stuff.
I called the preprocess_constraints functions in lra_set_insn_recog_data
rather than setup_operand_alternative because lra_set_insn_recog_data
already has a local constraints array (needed for asms).
setup_operand_alternative is now only called in the uncached case.
Thanks,
Richard
