  fix Issue 14828 - duplicate symbol __ModuleInfoZ

- always emit __arrayZ/__assertZ/__unittest_failZ helpers (even in release)
  to avoid linkage issues when instantiating a template of that module
  with different compiler flags

- also fixes Issue 14748 - Removing std.stdio import causes 2x increase in "Hello, world"
  same underlying issue, some undefined helper function drag in a different
  module which happens to have weak definitions of those helpers
