ilo: add TOY_OPCODE_DO

We used to give BRW_OPCODE_DO a special meaning, while we should have used
TOY_OPCODE_DO.
ilo: avoid brw_wm_barycentric_interp_mode in compiler

In preparation for genhw.
ilo: add genhw headers

All except genhw.h are generated by https://github.com/olvaffe/envytools/.
intel_chipset.h is deprecated.
ilo: scripted conversion to genhw headers

Hopefully my four hundred line sed script is correct.
ilo: use only defines from genhw headers

Stop including classic driver headers in genhw.h, with some formatting fixes.
ilo: remove unused headers

Remove intel_*.h.  brw_*.h is still needed by the state dumper and
disassembler.
ilo: remove GPE command size estimation

Use size defines from genhw.
ilo: remove GPE state size estimation

Use size defines from genhw.
