Description: Adds PytatoParallelPyOpenCLArrayContext, which is like PytatoPyOpenCLArrayContext but parallelizes over the device. Based on @kaushikcfd's work in #216. This version generalizes that code to work with fused loops. The basic procedure is: Collect instructions that share inames into sets. Find the "outer" inames (i.e., inames shared between all instructions) in each of those sets. Parallelize over those. cc @lukeolson ⚠️ Currently WIP. TODO: Figure out why some tests are failing (here and in inducer/loopy#1010) Re-run profiling on Tuolumne to make sure I haven't messed anything up Merge loopy deps Add docs
