I plan to revert this once the buffer deallocation pass is working properly with the sparse compiler. The plan is to fix all memory leaks first, so that I can easily spot issues/regressions while working on the buffer deallocation pass.

I could move the op to `Dialect/Test/TestOps.td` in the mean time and rename it to `test.sparse_tensor.has_runtime_library`. But so far we don't seem to have dialect-specific test ops in there. Alternatively, I could also rename it to `sparse_tensor.test.has_runtime_library`.
