<pre>Ungine Valley fails to run due to "intel_do_flush_locked failed: Input/output
error" with latest Mesa.
This started to happen on BDW/BSW/SKL ~31st of March, but it doesn't happen on
IVB/HSW/BYT,
Automated bisecting on BDW & SKL gave the same commit as trigger to this:

i965: Remove NOP insertion kludge in scheduler.
Instead of removing every instruction in add_insts_from_block(), just
move the instruction to its scheduled location. This is a step towards
doing both bottom-up and top-down scheduling without conflicts.
Note that this patch changes cycle counts for programs because it begins
including control flow instructions in the estimates.

---------------------------------------------------------
This happens both on:
- Ubuntu 15.10 with DRI3 + latest 4.6-rc kernel & latest X, and
- Ubuntu 16.04 with DRI2 + Ubuntu kernel (i.e. 4.4 + 4.6 i915 forklift) & X
(There have been similar issues with SynMark Multithread test, but those aren't
100% reproducible like this.)</pre>
