Please see PR1317 and PR1318. I believe you're running into the same
issue. Briefly, the issue is that option processing has changed to not
be so oriented towards static initialization time. This has changed the
order of things and now your option is not recognized because it hasn't
been registered properly.

Yes, this isn't your bug.

These are probably the result of changes to the CommandLine.cpp file in
the last few days. All LLVM tools use a common facility for processing
command line options.

No, the registration mechanism is the same.
