--------------------+-----------------------
 We haven't built clang without the static analyzer in a long time, it
 appears. On clang-9.0, it can't be disabled due to the above error.

 It can be disabled on clang-3.7. Somewhere along the line the cmake build
 system made it so that it can't be disabled, and yet there is an option
 still to disable it.

 Likely have to enable and disable the relevant options as a group (which I
 suppose suggests an upstream bug to fix, as if you turn off the analyzer,
 you shouldn't error out if you don't turn off ARCMT as well).

 I am not sure at present how far back this "error" goes -- possibly all
 the way back to the start of the cmake build system that we defaulted to
 in clang-3.8, but will have to check. In the standard cmake build of
 clang, both the analyzer and ARCMT default to ON, so perhaps nobody has
 built clang with the analyzer OFF in a long time...
