r600g/sb: Enable SB for geometry shaders

Graphics / Mesa 3D Graphics Library / Mesa - Glenn Kennard [gmail.com] - 7 April 2015 17:18 UTC

Add SV_GEOMETRY_EMIT special variable type to track the implicit dependencies between CUT/EMIT_VERTEX/MEM_RING instructions so GCM/scheduler doesn't reorder them.

Mark emit instructions as unkillable so DCE doesn't eat them.

Enable only for evergreen/cayman as there are a few unexplained GS piglit regressions on R6xx/R7xx with SB enabled otherwise.
