i965/gen6: Fix HiZ hang in WebGL Google Maps
Emitting flushes before depth and hiz resolves at the top of blorp's
state emission fixes the hang. Marchesin and I found the fix
experimentally, as opposed to adhering to a documented hardware
workaround. A more minimal fix likely exists, but this gets the job
done.
Fixes HiZ hangs in the new WebGL Google maps on Sandybridge Chrome OS.
Tested by zooming in and out continuously for 2 hours.
