i965: Map GL_PATCHES to 3DPRIM_PATCHLIST_n.
Inspired by a patch by Fabian Bieler.
Fabian defined a _3DPRIM_PATCHLIST_0 macro (which isn't actually a valid
topology type); I instead chose to make a macro that takes an argument.
He also took the number of patch vertices from _mesa_prim (which was set
to ctx->TessCtrlProgram.patch_vertices) - I chose to use it directly to
avoid the need for the VBO patch.
v2: Change macro to 0x20 + (n - 1) instead of 0x1F + n to better match
the documentation (suggested by Ian).
