lima: add summary report for shader-db
Very basic summary, loops and gpir spills:fills are not updated yet and are only there to comply with the strings to shader-db report.py regex. For now it can be used to analyze the impact of changes in instruction count in both gpir and ppir. The LIMA_DEBUG=shaderdb setting can be useful to output stats on applications other than shader-db.
