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