How about creating a new dg-add-options for freorder?
proc add_options_for_freorder { flags } {
     return "$flags -freorder-blocks-and-partition -fprofile-use"
}


proc check_effective_target_freorder {} {
     return [check_no_compiler_messages freorder object {
     void foo (void) { }
     } [add_options_for_freorder ""]]

I don't know that tcl syntax but apparently this is done already for a 
number of other cases. So, probably the right thing to do.

You might want to coordinate with Maxim ostapenko who's currently 
working on another -fprofile-use patch. Hopefully not one that disables 
-freorder-blocks-and-partition if it can't find .gcda files.
