FYI: remove some dead code

[Tom Tromey <tromey at redhat dot com>]

I'm checking this in on the trunk.

This removes some dead code.  TYPE_CODE_TEMPLATE and
TYPE_CODE_TEMPLATE_ARG are dead because nothing ever creates
types using these.  The corresponding fields in cplus_struct_type
are dead because nothing ever sets or uses them.

Built and regtested on x86-64 (compile farm).
