I had thought that get_prev_frame's call to inside_entry_func() had
been disabled pending a demonstration that it's needed.  Hmm...  I see
I was getting this confused with the code corresponding to
inside_entry_file().

Okay, that means that frv-tdep.c's use of inside_entry_func() can go
away.  I'll get rid of it.
