commit c7ae7675cf726c343a1db3e27e3e5665cb485271
Author: Christian Biesinger <cbiesinger@google.com>
Date:   Thu Sep 19 13:33:35 2019 +0900

    Move arm_apcs_32 extern declaration to header
    
    Instead of having several extern declarations for arm_apcs_32
    in a few .c files, declare it in arm-tdep.h. This file is already
    included from these .c files.
