freedreno/ir3: create fragcoord instructions in input block
This was somehow working to create the instructions in a random block,
and use the value in other blocks, by dumb luck. But two-pass-RA's
better choice of register assignment causes a couple dEQPs to start
failing without this fix:
dEQP-GLES3.functional.shaders.metamorphic.bubblesort_flag.variant_1
dEQP-GLES3.functional.shaders.metamorphic.bubblesort_flag.variant_2
