test/gem_storedw_*: tune some more
MI_*/PIPE_CONTROL writes need to be in DOMAIN_INSTRUCTION, because
that is what mesa uses and I plan to use this to work around a
gen6 ppgtt issue.
Also testing with intentionally b0rked GFX_MODE on my snb shows that
we need to increase the loop counter a bit to reliably hit the tlb
invalidation problem. Test still completes within a few seconds.
