The previous CL introduced stack objects. This CL removes the old ambiguously live liveness analysis. After this CL we're relying on stack objects exclusively. Update a bunch of liveness tests to reflect the new world. Fixes #22350 Change-Id: I739b26e015882231011ce6bc1a7f426049e59f31 Reviewed-on: https://go-review.googlesource.com/c/134156 Reviewed-by: Austin Clements <austin@google.com> Reviewed-by: Cherry Zhang <cherryyz@google.com>
