  Consolidate parallel compilation in front-end
  
  This cleans up the multiple compilation task implementations in the
  backends and consolidates them in the front-end.  The front-end is then
  able to do the compilation in an unlocked tail call instead if
  desired (in a future change).
  
  This change is in preparation for having the program link tasks directly
  wait on the shader compilation tasks.  As a result, the "shader resolve"
  should not be needed to access the shader compilation results; it should
  be enough to wait for the compilation job.  This change therefore moves
  post-processing of results to the compilation job itself as they did not
  need to actually be done after compilation is done (merely after
  translation is done).  As a side effect, shader substition and other
  debug features should now work for the GL backend as they are now done
  before back-end compilation.
