[Mesa-dev] [PATCH] i965: Add defines for tessellation stages

[Kenneth Graunke]

From: Chris Forbes <chrisf at ijw.co.nz>

v2 (Ken):
- Squash together commits for HS, DS, and TE, as well as fixes.
- Add INTEL_MASK variants so we can use SET_FIELD if we want.
- Rename GEN7_HS_INSTANCE_CONTROL to GEN7_HS_INSTANCE_COUNT to match
  the documentation.
- Add some more fields from the PRMs.
- Add Broadwell variants.
