a7c3899c06 perf symbols: No need to check if sym->name is NULL 
As it is an array, so will always evaluate to 'true', as reported by
clang:

  builtin-sched.c:2070:19: error: address of array 'sym->name' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
                  if (sym && sym->name) {
                          ~~ ~~~~~^~~~
  1 warning generated.

So just ditch all those useless checks.

a8763445f6 perf symbols: Print symbol offsets conditionally 
The __symbol__fprintf_symname_offs() always shows symbol offsets.  So
there's no difference between 'perf script -F ip,sym' and 'perf script
-F ip,sym,symoff'.  I don't think it's a desired behavior..

bfbba189b6 perf symbols: Move fprintf routines to separate object file 
To disentangle symbol printing from all the code related to symbol
tables, resolution of addresses to symbols, etc.
