Until now, the assembler had relocation-related fields added to struct
brw_instruction. This changes the size of the structure and break code
assuming the opcode structure is really 16 bytes, for instance the
emission code in brw_eu_emit.c.
With this commit, we build on the infrastructure that slowly emerged in
the few previous commits to add a relocatable instruction with the
needed fields.

Finally merge both brw_structs.h from mesa. One detail has risen in that
last commit, the msg_control field of data port message descriptors.
Mesa's msg_control field is sometimes split with messages-specific
fields where the assembler (at least for recent generations) exposes the
full msg_control value in the send instruction.
As libva's shaders encodes the full msg_control value in its send
instructions, I've chosen to not take the split msg_control from mesa.
It's absolutely possible to have a patch fixing that divergence at some
later point.
I've also kept a hack introduced with ironlake to not have to rewrite
shaders (that encode msg_control in the text, remember), and thus
creates a another difference with Mesa.
- GLuint msg_control:3;
- GLuint msg_type:3;
+ GLuint msg_control:4;
+ GLuint msg_type:2;
Once again, I've made sure that re-generating libva's shaders don't show
any difference.

The purpose of this commit is to synchronize opcode definitions across

We ended up with 2 structures that where exactly the same, so just use
one, which happens to be the one Mesa has.

I had to drop how mesa splits msg_control as the current assembly
language gives access the the whole msg_control field.
Recompiling the xorg and the intel driver of libva shaders doesn't show
any difference in the assembly created.

Two changes there, a field has been renamed and one bit of padding is
now used for compressed instructions.
