add pipelined predict-and-recompute CG variant

Tyler Chen requested to merge tchen01/petsc:tchen01/ksp-pipeprcg into master

This is a new CG variant which (pipelined predict-and-recompute CG) allows the global reductions and matrix vector products in each iteration to occur simultaneously. The numerical properties may be better than pipecg.
