assembler: Rename dp_gen6 to gen6_dp and sync with Mesa's

Browse Source 
The purpose of this commit is to synchronize opcode definitions across
the gen4asm assembler and mesa.

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.
