	* amd64-tdep.c (amd64_byte_names): New.
	(amd64_word_names): Likewise.
	(amd64_dword_names): Likewise.
	(amd64_pseudo_register_name): Likewise.
	(amd64_pseudo_register_read): Likewise.
	(amd64_pseudo_register_write): Likewise.
	(amd64_init_abi): Set num_byte_regs, num_word_regs, num_dword_regs
	and num_mmx_regs.  Call set_gdbarch_pseudo_register_read,
	set_gdbarch_pseudo_register_write and
	set_tdesc_pseudo_register_name.  Don't call
	set_gdbarch_num_pseudo_regs.  Don't set mm0_regnum.
	
	* i386-tdep.c (i386_num_mmx_regs): Removed.
	(i386_num_pseudo_regs): Likewise.
	(i386_byte_names): New.
	(i386_word_names): Likewise.
	(i386_byte_regnum_p): Likewise.
	(i386_word_regnum_p): Likewise.
	(i386_mmx_regnum_p): Updated.
	(i386_pseudo_register_name): Make it global.  Handle byte and
	word pseudo-registers.
	(i386_pseudo_register_read): Likewise.
	(i386_pseudo_register_write): Likewise.
	(i386_pseudo_register_type): Handle byte, word and dword
	pseudo-registers
	(i386_register_reggroup_p): Don't include pseudo
	registers, except for MXX, in any register groups.  Don't
	include pseudo byte, word, dword registers in general_reggroup.
	(i386_gdbarch_init): Set num_byte_regs, num_word_regs,
	num_dword_regs, al_regnum, ax_regnum and eax_regnum.  Put MMX
	pseudo-registers after word pseudo-registers.  Call
	set_gdbarch_num_pseudo_regs after calling gdbarch_init_osabi.
	
	* i386-tdep.h (gdbarch_tdep): Add num_mmx_regs, num_byte_regs,
	al_regnum, num_word_regs, ax_regnum, num_dword_regs and
	eax_regnum.
	(i386_byte_regnum_p): New.
