This series makes end_sequence return the insn sequence that it ends, so that callers don't need to call get_insns separately. It also updates many callers to take advantage of the new return value.
Although this kind of refactoring/API change can in general make backports harder, I think in this case it would be enough to backport the first patch along with the first backport that needs it. We did something similar for force_lowpart_subreg. See the covering note in patch 1 for more discussion about the pros and cons of the interface change. The first patch is a prerequisite for a genemit series that I'm hoping to post tomorrow. Bootstrapped & regression-tested on aarch64-linux-gnu & x86_64-linux-gnu. Also tested against "all" config.gcc cases using config/config-list.mk. OK to install?
