Dimitry points out it did get merged (r325082), so I must have been
testing a version of 6.0.0 before the final release.

Testing again now, with:
FreeBSD clang version 6.0.0 (tags/RELEASE_600/final 326565) (based on
LLVM 6.0.0)
confirms it emits calls to __x86_indirect_thunk_r11; sorry for the false alarm.
