turnip: Reduce the pipeline's CS allocation a bit.

Browse source 
We don't return unused space to the suballocator, so it's a little useful
to limit how much we overallocate to reduce memory footprint.  I took a
look through the tu_cs_emit_array() calls and accounted for a couple of
them in the variant-specific space calculation, then dropped the base
allocation by factors of 2 until we started throwing asserts.
