        PR 25127
        * config/rs6000/rs6000.c (first_altivec_reg_to_save): On Darwin,
        save Altivec registers in an eh_return function.
        (compute_vrsave_mask): Likewise.
        (rs6000_stack_info): Correct AIX/Darwin stack alignment computation
        for saving Altivec registers.
        (rs6000_emit_prologue): Don't allocate stack twice in
        eh_return function.  Correct expected value of altivec_save_offset
        when using save_world.  Describe save of R0 to stack when using
        save_world.  Describe stack pointer adjustment when using
        save_world.  Remove duplicated eh_return parameter register saving.
        Update sp_offset variable after save_world.
        * config/rs6000/t-darwin (LIB2FUNCS_STATIC_EXTRA): Remove
        darwin-world.asm.
        (LIB2FUNCS_EXTRA): Add darwin-world.asm.
        * config/rs6000/darwin.h (SUBTARGET_OVERRIDE_OPTIONS): -m64
        implies Altivec.
