i965/Gen6-7: Do not replace texcoords with point coord if not drawing points
Fixes broken rendering in Windows-based QtQuick2 apps run through Wine. This library sets all texture units' GL_COORD_REPLACE, leaves point sprite mode enabled, and then draws a triangle fan. Will need a slightly different fix for Gen4-5, but I don't have my old machines in a usable state currently. V2: - Simplify patch -- the real changes are no longer duplicated across the Gen6 and Gen7 atoms. - Also don't clobber attr overrides -- which matters on Haswell too, and fixes the other half of the problem - Fix newly-introduced warnings V3: - Use BRW_NEW_GEOMETRY_PROGRAM and brw->geometry_program rather than core flag and state; keep the state flags in order.
