Lowering IO to temps leads to problems with RA with piglit
   spec@glsl-1.50@execution@geometry@max-input-component

Not doing so results in an assertion failure with piglit
   spec@glsl-1.50@execution@geometry@dynamic_input_array_index

because not all indirect IO access is lowered. Using
nir_lower_indirect_derefs works around this limitations.

v2: Fix formatting (Patrick Lerda)

Fixes: 1186c73c6 (r600: implement gs indirect load_per_vertex_input)
