Comment (by rwbarton):

 The status here is currently:

 * Visible type applications with -fhpc are fixed by the above patch for
 HEAD

 * Merged to 8.0 by d56d11ffff419875a1fc08e2ff470a5c8bd8785f

 * Richard is looking into redesigning the representation of visible type
 applications in HsExpr, I believe. Not absolutely critical for 8.0, but
 for the sake of GHC API users, better to change HsExpr once, than now and
 again in 8.2.
