From: Trevor Saunders <tsaund...@mozilla.com>

Hi,

This changes all callers of INSN_DELETED_P to use one of insn->deleted () 
insn->set_deleted () or insn->set_undeleted () depending on what they're doing 
(set_deleted / set_undeleted seem somewhat clearer to me than = 0 / 1).

bootstrapped + regtested on x86_64-unknown-linux-gnu, and run through
config-list.mk with a couple other patches. ok?

        * cfgrtl.c, combine.c, config/arc/arc.c, config/mcore/mcore.c,
        config/rs6000/rs6000.c, config/sh/sh.c, cprop.c, dwarf2out.c,

        reload1.c, reorg.c, resource.c, sel-sched-ir.c: Replace INSN_DELETED_P
        macro with staticly checked member functions.
        * rtl.h (rtx_insn::deleted): New method.
        (rtx_insn::set_deleted): Likewise.
        (rtx_insn::set_undeleted): Likewise.
