rs6000: Use LR_REGNO instead of constant 65

rs6000: Use LR_REGNO instead of constant 65

Many places still use 65 instead of the symbolic constant LR_REGNO.  This
fixes them all (I looked for the string "65" only, in config/rs6000/ only,
I didn't read all code :-) )

I left it in *restore_world because Iain will remove it there soon.

	* config/rs6000/altivec.md (*save_world, *save_vregs_<mode>_r11,
	save_vregs_<mode>_r12, *restore_vregs_<mode>_r11,
	*restore_vregs_<mode>_r12): Use LR_REGNO instead of 65.
	* config/rs6000/darwin.md (load_macho_picbase, load_macho_picbase_si,
	load_macho_picbase_di, *call_indirect_nonlocal_darwin64,
	*call_nonlocal_darwin64, *call_value_indirect_nonlocal_darwin64,
	*call_value_nonlocal_darwin64, reload_macho_picbase,
	reload_macho_picbase_si, reload_macho_picbase_di): Ditto.
	* config/rs6000/rs6000.h (RETURN_ADDR_IN_PREVIOUS_FRAME): Ditto.
	* config/rs6000/rs6000.md (*save_gpregs_<mode>_r11,
	*save_gpregs_<mode>_r12, *save_gpregs_<mode>_r1,
	*save_fpregs_<mode>_r11, *save_fpregs_<mode>_r12,
	*save_fpregs_<mode>_r1): Ditto.
	* config/rs6000/spe.md (*save_gpregs_spe, *restore_gpregs_spe,
	*return_and_restore_gpregs_spe): Ditto.
