PATCH: Remove amd64_register_name

["H.J. Lu" <hongjiu.lu@intel.com>]

Hi,

amd64_register_name is the same as i386_register_name. There is no
need for it.  This patch removes it.  Tested on Linux/x86-64 and
Linux/x86-64 with AVX.  OK to install?

Thanks.

	* amd64-tdep.c (amd64_register_name): Removed.
	(amd64_init_abi): Don't call set_gdbarch_register_name.

	* i386-tdep.c (i386_ymmh_regnum_p): Make it static.

	* i386-tdep.h (i386_ymmh_regnum_p): Removed.
