i965/disasm: Actually disassemble Gen7+ URB opcodes. 

I never bothered implementing the disassembler for Gen7+ URB opcodes, so
we were just disassembling them as Ironlake/Sandybridge ones.  This
looked pretty bad when running Paul's GS EndPrimitive tests, as the
"write OWord" message was decoded at ff_sync, which doesn't exist.
