Made the coarse autobisect-script even better with git bisect skip.

Bisected the problem to first bad commit:

    drm/i915: Defer enabling rc6 til after we submit the first batch/context

Manually tested good and bad commit, checks out.

Tested with i915.enable_rc6=0, bad is still bad.

Kernels compiled without debugging options for performance reasons.
