Use conventional prefix/suffix for function calls.

Previously a function call with no return value generated:

  prefix();
  suffix();
  function();

The intent was so the prefix and suffix calls in the function body wouldn’t overlap with the prefix and suffix calls of the function call.  However, this is doomed to be inconsistent with a function call with a return value:

  prefix();
  print(function());
  suffix();

Thus since overlaping must exist, both types of function calls should have consistent suffix locations.
