nvc0/ir: per-patch vars are in a separate address space

There's no need to attempt to avoid overlapping generic i/o with patch
i/o. By the same token, we can't merge patch and non-patch loads/stores.

This fixes at least the

  tes-both-input-array-*-index-rd

tessellation variable-indexing tests.
