radeonsi: move PSIZE and CLIPDIST unique IO indices after GENERIC
Heaven LDS usage for LS+HS is below. The masks are "outputs_written"
for LS and HS. Note that 32K is the maximum size.
Before:
heaven_x64: ls=1f1 tcs=1f1, lds=32K
heaven_x64: ls=31 tcs=31, lds=24K
heaven_x64: ls=71 tcs=71, lds=28K
After:
heaven_x64: ls=3f tcs=3f, lds=24K
heaven_x64: ls=7 tcs=7, lds=13K
heaven_x64: ls=f tcs=f, lds=17K
All other apps have a similar decrease in LDS usage, because
the "outputs_written" masks are similar. Also, most apps don't write
POSITION in these shader stages, so there is room for improvement.
(tight per-component input/output packing might help even more)
It's unknown whether this improves performance.
