i965: allow 8 user clip planes on CTG+
There's no need to use a clip flag for NEGW on these gens, so
no reason we can't just enable 8 planes.
V2: - Bump (and document!) MAX_VERTS in the clip code.
- Fix clip flag masks in the clip unit state and in the shader
prolog
- Move this to the end of the series for less breakage.
