Won't that leave bits of GNAT broken?  I think it uses __builtin_setjmp
explicitly.

Also, it has occured to me that my solution does not fix the whole
problem.  Normally, emit_indirect_jump is used within a function (for
instance, TRY_FINALLY_EXPR, or computed goto).  For those mov pc is
appropriate.  But for __builtin_setjmp it isn't.  keep_stack_depressed
even has the hideous:
          jump_insn = emit_jump_insn (gen_indirect_jump (retaddr));
