gallium/ddebug: new pipe for hang detection and driver state dumping (v2)

v2: lots of improvements

This is like identity or trace, but simpler. It doesn't wrap most states.

Run with:
  GALLIUM_DDEBUG=1000 [executable]
where "executable" is the app and "1000" is in miliseconds, meaning that
the context will be considered hung if a fence fails to signal in 1000 ms.

If that happens, all shaders, context states, bound resources, draw
parameters, and driver debug information (if any) will be dumped into:
  /home/$username/dd_dumps/$processname_$pid_$index.

Note that the context is flushed after every draw/clear/copy/blit operation
and then waited for to find the exact call that hangs.

You can also do:
  GALLIUM_DDEBUG=always
to do the dumping after every draw/clear/copy/blit operation without
flushing and waiting.

Examples of driver states that can be dumped are:
- Hardware status registers saying which hw block is busy (hung).
- Disassembled shaders in a human-readable form.
- The last submitted command buffer in a human-readable form.

i965/bdw: Fix 3DSTATE_VF_INSTANCING when the edge flag is used

When the edge flag element is enabled then the elements are slightly
reordered so that the edge flag is always the last one. This was
confusing the code to upload the 3DSTATE_VF_INSTANCING state because
that is uploaded with a separate loop which has an instruction for
each element. The indices used in these instructions weren't taking
into account the reordering so the state would be incorrect.

v2: Use nr_elements instead of brw->vb.nr_enabled so that it will cope
    when gl_VertexID is used.

i965: Swap the order of the vertex ID and edge flag attributes

The edge flag data on Gen6+ is passed through the fixed function hardware as
an extra attribute. According to the PRM it must be the last valid
VERTEX_ELEMENT structure. However if the vertex ID is also used then another
extra element is added to source the VID. This made it so the vertex ID is in
the wrong register in the vertex shader and the edge attribute is no longer in
the last element.

v2: Also implement for BDW+

v3 [by Ben]: Remove 10.5 tag. Too late.
