MAX_VARYINGS_INCL_PATCH subtracts VARYING_SLOT_VAR0 giving us a size
that's too small, so BITSET_SET writes words out of bounds, corrupting
the stack and causing all kinds of chaos. VARYING_SLOT_TESS_MAX is
the right value to use here, as it's the largest location.
Closes: 2002
Fixes: ee2050b111 ("nir: Use BITSET for tracking varyings in lower_io_arrays")
