bug#54437: 28.0.92; command-modes returns nil for native compiled functions

[Knut Anders Hatlen]

With Emacs built with --with-native-compilation, command-modes appear to
return nil for native compiled functions:

(progn
  (load "help-mode")
  (command-modes 'help-view-source))
=> nil

When the function is interpreted or byte-compiled, it returns the
expected result:

(progn
  (load "help-mode.el")
  (command-modes 'help-view-source))
=> (help-mode)

(progn
  (load "help-mode.elc")
  (command-modes 'help-view-source))
=> (help-mode)
