i965 gs: Remove unnecessary mapping of key->primitive.
Previously, GS generation code contained a lookup table that mapped
primitive types POLYGON, TRISTRIP, and TRIFAN to TRILIST, mapped
LINESTRIP to LINELIST, and left all other primitives unchanged. This
was silly, because we never generate a GS program for those primitive
types anyhow.
This patch removes the unnecessary lookup table.
