--- Comment #21 from Sanjay Patel <spatel+llvm at rotateright.com> ---
This was at least 3 independent bugs in 1 report. I'm going to mark this as
fixed because we are generating 'blsr' in the simplified cases mentioned so far
after these commits:

https://reviews.llvm.org/rL323437
https://reviews.llvm.org/rL324839
https://reviews.llvm.org/rL325018

If we're still failing to produce blsr in other cases or in your environment,
please file another bug. Thanks!
