nir/from_ssa: Clean up parallel copy handling and document it better
Previously, we were doing a lazy creation of the parallel copy instructions. This is confusing, hard to get right, and involves some extra state tracking of the copies. This commit adds an extra walk over the basic blocks to add the block-end parallel copies up front. This should be much less confusing and, consequently, easier to get right. This commit also adds more comments about parallel copies to help explain what all is going on. As a consequence of these changes, we can now remove the at_end parameter from nir_parallel_copy_instr.
