ARM parts, no further notes.

Thanks,
Chung-Lin

        ARM_BUILTIN_THREAD_POINTER.
        (arm_init_tls_builtins): Remove function.
        (arm_init_builtins): Remove call to arm_init_tls_builtins().
        (arm_expand_builtin): Remove ARM_BUILTIN_THREAD_POINTER case.
        (arm_expand_builtin_thread_pointer): Add hook function for
        TARGET_EXPAND_BUILTIN_THREAD_POINTER.
