    > 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.
