There was a lot of duplication going on... Mark as basic while we're at
it as these should never fail.
v2: add to .gitignore

Also start to shortly explain testcases with an easily-greppable
header like this:

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.

Add a couple of simple store dword tests to test memory coherence.
gem_storedw_loop simply executes a batch that continually stores an
incremented value to a target buffer object, checking the results after
each batch completes.
gem_storedw_batches_loop does the same thing, but creates a new command
batch buffer for each iteration, which can exercise the buffer creation
code. This test is based on one from Andrzej Kacprowski from Intel.
