This adds a filter option for --trace-turbo, --trace-turbo-graph
and --trace-turbo-scheduled. The filter is a pattern that matches
function names in this way:
   "*"      all; the default
   "-"      all but the top-level function
   "-name"  all but the function "name"
   ""       only the top-level function
   "name"   only the function "name"
   "name*"  only functions starting with "name"
   "~"      none; the tilde is not an identifier
