I'd rather not.  At some point I wanted to refactor the main opt
pipeline to work like this and skip some of the early passes there
if we did _not_ inline ...

-Og -fno-early-inline will still do always inline inlining early.

  /* Even when not optimizing or not inlining inline always-inline
     functions.  */
