        * config/i386/i386.md (allocate_stack_worker_64): Make sure 
argument operand in
        rax isn't removed.

        * gcc-c.torture/execute/pr36321.c: New.

This patch is bootstraped and regression tested. This patch affects 4.3 
branch, too.
Is this patch ok for apply on trunk ?

Cheers
  Kai
