    Original Commit Message:
    
        Code object iteration was missing logic for RELATIVE_CODE_TARGET
        reloc entries. Garbage collection could thus miss objects that were
        referenced only as targets of pc-relative calls or jumps.
    
        RELATIVE_CODE_TARGETs are only used on arm, mips, and s390 and only
        at mksnapshot-time.
    
        This exposed another issue in that the interpreter entry trampoline
        copy we generate for profiling *did* contain relative calls in
        runtime-accessible code. This is a problem, since code space on arm is,
        by default, too large to be fully addressable through pc-relative
        calls. This CL thus also disables the related
        FLAG_interpreted_frames_native_stack feature on arm.
    
        objects.
