Comment (by simonmar):

 Yes, it looks like all of `GHC.Exts.{breakpoint,breakpointCond,Opaque}`
 are dead code, as are these in `PrelNames`:

 {{{
 breakpointName    = varQual gHC_BASE (fsLit "breakpoint") breakpointIdKey
 breakpointCondName= varQual gHC_BASE (fsLit "breakpointCond")
 breakpointCondIdKey
 breakpointAutoName= varQual gHC_BASE (fsLit "breakpointAuto")
 breakpointAutoIdKey
 opaqueTyConName   = tcQual  gHC_BASE (fsLit "Opaque")   opaqueTyConKey
 }}}

 Would someone like to go ahead and remove them?
