Remove warning about very large functions.

4 years ago, commit 49d7717 removed
OUTLINING_LIMIT which was the only actionable item a user could do to avoid
this warning. Suggesting to compile with -Oz when the user is already
compiling with -Oz is just supidly insulting and not contructive user
feedback.

It is not Emscripten's job to have opinions about the size of functions.

Fixes <emscripten-core#20811>.
