PATCH: PR gdb/11265: "infor reg sse" doesn't work on Linux/x86-64

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

Linux/x86-64 overides i386_register_reggroup_p with
amd64_linux_register_reggroup_p, which calls
default_register_reggroup_p. It makes Linux/x86-64 different from
other x86-64 targets where "infor reg sse" works.  This patch makes
"infor reg sse" to work on Linux/x86-64 like other x86-64 targets.  OK
to install?

Thanks.
