This is the refreshed main patch.  I've rearranged the preprocess_constraints
code into three functions so that LRA can use it in patch 5.

Thanks,

gcc/
        * recog.h (operand_alternative): Convert reg_class, reject,
        matched and matches into bitfields.
        (preprocess_constraints): New overload.
        (preprocess_insn_constraints): New function.
        (preprocess_constraints): Take the insn as parameter.
        (recog_op_alt): Change into a pointer.
        (target_recog): Add x_op_alt.
        * recog.c (asm_op_alt): New variable.
        (recog_op_alt): Change into a pointer.
        (preprocess_constraints): New overload, replacing the old function
        definition with one that doesn't use global state.
        (preprocess_insn_constraints): New function.
        (preprocess_constraints): Use them.  Take the insn as parameter.
        Use asm_op_alt for asms.
        (recog_init): Free existing x_op_alt entries.
        * ira-lives.c (check_and_make_def_conflict): Make operand_alternative
        pointer const.
        (make_early_clobber_and_input_conflicts): Likewise.
        (process_bb_node_lives): Pass the insn to process_constraints.
        * reg-stack.c (check_asm_stack_operands): Likewise.
        (subst_asm_stack_regs): Likewise.
        * regcprop.c (copyprop_hardreg_forward_1): Likewise.
        * regrename.c (build_def_use): Likewise.
        * sched-deps.c (sched_analyze_insn): Likewise.
        * sel-sched.c (get_reg_class, implicit_clobber_conflict_p): Likewise.
        * config/arm/arm.c (xscale_sched_adjust_cost): Likewise.
        (note_invalid_constants): Likewise.
        * config/i386/i386.c (ix86_legitimate_combined_insn): Likewise.
        (ix86_legitimate_combined_insn): Make operand_alternative pointer
        const.

OK.
