One consequence of paren.el's not being preloaded is that in a
native-compilation build, Emacs begins compiling paren.el as soon as
it starts, and that causes it also to compile about a dozen other
files that comp.el requires.  Should we perhaps native-compile all the
prerequisites of comp.el as part of COMPILE_FIRST when we build Emacs?
