rs6000.c (rs6000_stack_info): Remove insn_chain_scanned.

2003-03-11  Aldy Hernandez  <aldyh@redhat.com>

        * config/rs6000/rs6000.c (rs6000_stack_info): Remove
        insn_chain_scanned.  Use insn_chain_scanned_p in machine_function.

        * config/rs6000/rs6000.h (machine_function): Add insn_chain_scanned_p.
