That was a problem in caching constant expressions when processing loads and stores.
I've recomitted patch with fix and test case. See r365215 (and r365188 which had alignment problem)

Just wanted to confirm, after reverting this, I was able to build and test LLD with ThinLTO enabled again, so this did cause the issue.

Unfortunately, I have not been able to come up with a reduced test case for the issue, so I will have to leave the instructions at "run check-lld with thinlto enabled".
