We tweak the tests marked as runnable in simulation to run more quickly,
more often then not at the expense of stress testing (which is of an
arguable interest for the initial bring up in simulation). Hopefully the
values chosen still test something, which is not always straightforward.
It does run quickly, the number on an IVB machines are:
$ time sudo IGT_SIMULATION=0 ./piglit-run.py tests/igt.tests foo
[...]
real 2m0.141s
user 0m16.365s
sys 1m33.382s
Vs.
$ time sudo IGT_SIMULATION=1 ./piglit-run.py tests/igt.tests foo
[...]
real 0m0.448s
user 0m0.226s
sys 0m0.183s

MI_MEM_VIRTUAL actually means use global gtt now, not setting the bit
means use ppgtt. On previous gens, not setting the bits ment 'use
physical memory'. So what, the usual confusion.
Note that for some odd reasong this is broken on gen6, but only on the
bsd ring. Unexpected.

We need to use _INSTRUCTION as the reloc domain because otherwise the
ppgtt pipe_control w/a for snb won't kick in and the test fails.
The storedw tests for blt and bsd are still disabled because the
corresponding patch to flag ppgtt support isn't merged upstream yet.
Without ppgtt these hang my snb here.

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