* findvar.c (find_var_value): Handle &function better.

Browse Source 
* TODO:  Document work needed on &fn and &array.
        * printcmd.c (print_address_symbolic):  New arg is the prefix
        to print if a name is printed.
        (print_address_demangle):  Honor "set print address" now.
        Use new arg above to improve spacing of output.
        * valprint.c (val_print):  When printing function pointers,
        print symbolic form too.
        * breakpoint.c (breakpoint_1):  Use new print_address_symbolic.
