* fwprop.c (try_fwprop_subst): Use set_unique_reg_note
to add the REG_EQ* note.
* see.c (see_merge_one_use_extension): Likewise.
* local-alloc.c (update_equiv_regs): Likewise. Also don't
turn REG_EQUAL notes into REG_EQUIV notes if the target
register may have more than one set.
* function.c (assign_parm_setup_reg): Use set_unique_reg_note.
* gcse.c (try_replace_reg): Likewise.
* alias.c (init_alias_analysis): Use find_reg_equal_equiv_note.
* calls.c (fixup_tail_calls): Likewise. Abort if there is
more than one REG_EQUIV note.
* reload1.c (gen_reload): Use set_unique_reg_note.
