EXT_draw_instanced doesn't work in GLES 2.0 - dispatch goes wrong
On crocus testing:
piglit ./bin/ext_draw_instanced-drawarrays
fails, due to the dispatch having a nop entry.
The code to detect when this should be filled into the dispatch looks wrong post python generator, but not sure where to fix it pre-python.
@idr @mareko @anholt maybe someone knows.
