I am sorry. It seems I have been using 'git bisect' wrong.

This is the breaking change:

commit 248ab61740c4082517424f5aa94b2f4e7b210d76 (HEAD)
Author: Jason Ekstrand <jason.ekstrand at intel.com>

    anv/cmd_buffer: Pull the core of flush_state into genX_cmd_buffer

And this seems to make more sense.
