r600: fix error filters compatibility

The shader-db functionality was interfering with the error
filters.

Two new options are added: R600_DEBUG=shaderdb and
R600_DEBUG=precompile. The option precompile is added
to maintain the compatibility with the shader-db repository.

This change fixes 22 of these tests:
deqp-gles31/functional/debug/error_filters/case_.*: warn pass
deqp-gles31/functional/debug/error_groups/case_.*: warn pass

Fixes: 28d6a5af25 ("r600: Add shader precompile and shader-db support.")
