We have seen an internal failure that may be caused by load/store register
renaming. I was not able to track down the problem so far.

I think it would be best to pick 8e3f59b45ae185cc9b4e3a817d7ac958f1d55976
([AArch64] Add option to enable/disable load-store renaming.) onto the 10.0. It
adds an option and defaults to disabled for AArch64 load/store register
renaming.
