According to our internal repository, these now dead functions were
added early in 2002 to implement hardware watchpoint support.  At the
time, there was a config/frv/tm-frv.h file and presumably one or more
of the watchpoint related macros called these functions.

For the moment, I'd like to leave these as dead code.  I'll try to
find some time to figure out how to make them non-dead, or failing that,
I'll delete them.

Thanks for bringing this to my attention.
