Bootstrapping clang release/17.x fails to build - ‘clang/Driver/Options.inc’ file not found

[jroelofs]

When bootstrapping clang, the stage 2 builds appear to sometimes fail due to a missing table gen file.

llvm-project/clang/include/clang/Driver/Options.h:49:10: fatal error: 'clang/Driver/Options.inc' file not found
   49 | #include "clang/Driver/Options.inc"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~

This seems to happen during stage 2 builds.

@EugeneZelenko so I get it right next time: why not release:fixed-in-main?

@jroelofs: I didn't remove this label intentionally. Probably we edited labels at the same time, so GitHub was confused.
