ac: fix broken elimination of duplicated VS exports
The renumbering code didn't take into account that multiple VS exports
can have the same PARAM index. This also significantly simplifies
the renumbering. Thankfully, we have piglits for this:
spec@arb_gpu_shader5@arb_gpu_shader5-interpolateatcentroid-packing
spec@glsl-1.50@execution@interface-blocks-complex-vs-fs
