Use ui_out_emit_tuple

Use ui_out_emit_tuple

This patch changes various places to use ui_out_emit_tuple,
eliminating a number of cleanups.  This patch only tackles "easy"
cases, which are ones where the cleanups in question were
block-structured and did not involve any changes other than the
obvious replacement.
