	* config/rs6000/rs6000.c (enum rs6000_reload_reg_type): Add new
	fields to the reg_addr array that describes the valid addressing
	mode for any register, general purpose registers, floating point
	registers, and Altivec registers.
	(FIRST_RELOAD_REG_CLASS): Likewise.
	(LAST_RELOAD_REG_CLASS): Likewise.
	(struct reload_reg_map_type): Likewise.
	(reload_reg_map_type): Likewise.
	(RELOAD_REG_VALID): Likewise.
	(RELOAD_REG_MULTIPLE): Likewise.
	(RELOAD_REG_INDEXED): Likewise.
	(RELOAD_REG_OFFSET): Likewise.
	(RELOAD_REG_PRE_INCDEC): Likewise.
	(RELOAD_REG_PRE_MODIFY): Likewise.
	(reg_addr): Likewise.
	(mode_supports_pre_incdec_p): New helper functions to say whether
	a given mode supports PRE_INC, PRE_DEC, and PRE_MODIFY.
	(mode_supports_pre_modify_p): Likewise.
	(rs6000_debug_vector_unit): Rearrange the -mdebug=reg output to
	print the valid address mode bits for each mode.
	(rs6000_debug_print_mode): Likewise.
	(rs6000_debug_reg_global): Likewise.
	(rs6000_setup_reg_addr_masks): New function to set up the address
	mask bits for each type.
	(rs6000_init_hard_regno_mode_ok): Use memset to clear arrays.
	Call rs6000_setup_reg_addr_masks to set up the address mask bits.
	(rs6000_legitimate_address_p): Use mode_supports_pre_incdec_p and
	mode_supports_pre_modify_p to determine if PRE_INC, PRE_DEC, and
	PRE_MODIFY are supported.
	(rs6000_output_move_128bit): Change to use {src,dest}_vmx_p for altivec
	registers, instead of {src,dest}_av_p.
	(rs6000_print_options_internal): Tweak the debug output slightly.
