        * i387-tdep.c (i387_supply_register): When called with NULL as a
        buffer, mark the register as not provided (to mirror the behavior
        of supply_register).
        (i387_supply_fxsave): Ditto.
        (i387_supply_fsave): Ditto (inherits the behavior from
        i387_supply_register).
