[Mesa-dev] [PATCH 1/8] i965: Add initial IS_HASWELL() macros.

[Kenneth Graunke]

For now, these all return 0, as I don't yet want to enable Haswell
support.  Eventually they will be filled in with proper PCI IDs.

Also add an is_haswell field similar to is_g4x to make it easy to
distinguish Gen7 and Gen7.5.
