* recog.h (alternative_class): New function.
(which_op_alt): Return a const recog_op_alt.
* reg-stack.c (check_asm_stack_operands): Update type accordingly.
(subst_asm_stack_regs): Likewise.
* config/arm/arm.c (note_invalid_constants): Likewise.
* regcprop.c (copyprop_hardreg_forward_1): Likewise. Don't modify
the operand_alternative; use alternative class instead.
* sel-sched.c (get_reg_class): Likewise.
* regrename.c (build_def_use): Likewise.
(hide_operands, restore_operands, record_out_operands): Update type
accordingly.
