This will allow the driver to capture all of its execution state to a
file for later debugging. intel_gpu_dump is limited in that it only
captures batchbuffers, and Mesa's captures, while more complete, still
capture only a portion of the state involved in execution.
This is a squash commit of a long series of hacking as we tried to get
the resulting traces to work in the internal simulator. It contains
contributions by Yuanhan Liu and Kenneth Graunke.

For example:
export INTEL_DEVID_OVERRIDE=0x162
If this variable is set, don't actually submit the batchbuffer to the
GPU, it probably contains commands for the wrong generation of hardware.
v2: Introduce a getter for the overridden devid, and avoid getenv per exec.

Every access to either the GTT or CPU pointer is supposed to be
proceeded by a set_domain ioctl so that GEM is able to manage the cache
domains correctly and for the following access to be coherent. Of
course, some people explicitly want incoherent, non-blocking access
which is going to trigger warnings by this patch but are probably better
served by explicit suppression.
v2: Also mark the pointers as inaccessible following the explicit unmap
and implicit unmap upon return to the cache.

The empty string used for the not case is replaced by the default
if-else clause and so causes the configure to fail in the absence of
valgrind. Which is not quite what was intended.
Instead use the common idiom of setting a variable depending on whether
the true or false branch is taken and emit the conditional code as a
second step.

This just gets packet name and length in place, with the remainder
unfinished. I've long since finished the work that got me started
fixing up the decode.
Since CC_STATE_POINTERS for gen6 and 7 are quite different but use the
same opcode, move gen6 out to a helper function too, so we can use a
helper function for gen7.
This puts the error message in a consistent location relative to the
packet, and while I'm here I made the error message a bit more
informative.
Now, most static length packets need to just declare their length in
the table and not worry.
The overflow checks were all thoroughly untested, and a bunch of the
ones I'm deleting were pretty broken. Now, in the case of overflow,
you just decode data of 0xd0d0d0d0, and instr_out prints the warning
message instead. Note that this still has the same issue of being
under-tested, but at least it's one place instead of per-packet.
A couple of BUFFER_FAIL uses are left where the length to be decoded
could be (significantly) larger than a page, and the decode didn't
just call instr_out (which doesn't dereference data itself unless it's
safe).
The .batch was generated using the dump-a-batch branch of
git://people.freedesktop.org/~anholt/mesa
using glxgears on gen7 hardware, using INTEL_DEVID_OVERRIDE for
non-gen7 (this means that offsets in the buffers for non-gen7 are 0!).
The .ref was generated by:
./test_decode tests/gen7-3d.batch -dump.
The .sh exists because you can't supply arguments to tests using the
simple automake tests driver. Something reasonable could be done
using automake's parallel-tests driver (in fact, a previous version of
the patch did that), but I was concerned that:
1) The parallel-tests driver is documented to be unstable -- they may
change interfaces on us later.
2) The parallel-tests driver hides the output of tests in .log files
scattered all over the tree, which was ugly and more painful to
work with.
v2: Actually add the batch files, add a .gitignore for the *-new.txt
files added after failures, and fix failure mode for undetected
chipset name.
