        * regs.h (struct target_regs): New field
        x_contains_allocatable_regs_of_mode.
        (contains_allocatable_regs_of_mode): New macro.
        * reginfo.c (init_reg_sets_1): Initialize it, and change
        contains_reg_of_mode so it includes global regs as well.
        * reload.c (push_reload): Use contains_allocatable_regs_of_mode
        rather than contains_regs_of_mode.
