Simplify code complexity of perms.cc (bug #65244) * perms.cc (GetPerms): Remove third input "do_sort". Merge code from GetPermsNoSort(). Use std::iota rather than hand-rolled for loop. * perms.cc (GetPermsNoSort): Delete function. * perms.cc (Fperms): Rename functions calls to GetPermsNoSort() to GetPerms(). Rewrite input validation error message to refer to input "V".
