Original commit message:

    Revert "s390: [arm] Add missing RELATIVE_CODE_TARGET iteration"

    This reverts commit 9d3cca1cd3ad7c6653cab1cdf111d356f33f77cd.

    Reason for revert: Only the test needs to be skipped on s390. Refer to this: https://crrev.com/c/1981505

    Original change's description:
    > s390: [arm] Add missing RELATIVE_CODE_TARGET iteration
    >
    > Port b766299d2c382cc9817e73225bbebe29ce62b9d1

    > 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.
