[binutils-gdb] add_location_to_breakpoint -> breakpoint::add_location

[Pedro Alves <palves@sourceware.org>]

https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=06615628294ceb515c045050a39cff4d66a20c1e

commit 06615628294ceb515c045050a39cff4d66a20c1e
Author: Pedro Alves <pedro@palves.net>
Date:   Fri May 6 19:18:48 2022 +0100

    add_location_to_breakpoint -> breakpoint::add_location
    
    Make add_location_to_breakpoint be a method of struct breakpoint.
    
    A patch later in the series will move this to base_breakpoint, but for
    now, it needs to be here.
