This patch-series implements the ARB_viewport_array for nvc0 and does
a little house-cleanig afterwords.
Tobias Klausmann (3):
nvc0: implement multiple viewports/scissors, enable ARB_viewport_array
nvc0: mark scissor in nvc0_clear_{}
nv50/ir: Remove NV50_SEMANTIC_VIEWPORTINDEX and its last consumer

Review comments sent; you should also add a separate patch that marks off ARB_viewport_array in GL3.txt and adds it to relnotes for 10.3.
