Base `DataFlowAnalysis::visit` returns `LogicalResult`, but wrappers's Sparse/Dense/Forward/Backward `visitOperation` doesn't. Sometimes it's needed to abort solver early if some unrecoverable condition detected inside analysis. Update `visitOperation` to return `LogicalResult` and propagate it to `solver.initializeAndRun()`. Only `visitOperation` is updated for now, it's possible to update other hooks like `visitNonControlFlowArguments`, bit it's not needed immediately and let's keep this PR small. Hijacked `UnderlyingValueAnalysis` test analysis to test it.
