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.
