 Don't use $ in the definition of (<**>) in GHC.Base

 ($) is special as Richard explains in the note at the top of the page.

 However, when adding the note he didn't remove this usage. Normally it
 didn't cause any problems as the optimiser optimised it away. However if
 one had the propensity to stick one's fingers into the depths of the
 inliner, it caused horrible idInfo panics.
