Sorry, I guess I should repeat here the argument I made on IRC.  It
would not work, because the GC will not find its roots.  With
--gcrootfinder=shadowstack, I think it will get confused by the
switches -- maybe I am wrong and it works anyway; but then I know for
sure that with --gcrootfinder=asmgcc it will definitely not work at
all.  (For reference, the JIT requires --gcrootfinder=asmgcc.)
