I use this code for the current user:

You should create either a twig macro, or a twig function.

Creating a macro is very simple, using your code:

{% macro admin_status(from_user) %}
  {% set from_user_is_admin = false %}
  {% for role in from_user.getRoles() %} 
      {% if role == 'ROLE_ADMIN' %}{% set from_user_admin = true %}{% endif %}
      {% if role == 'ROLE_SUPER_ADMIN' %}{% set from_user_admin = true %}{% endif %}
  {% endfor %}
  {% if from_user_admin == false %}THIS USER IS NOT ADMIN{% endif %}
{% endmacro %}

You can then use it in the same file as {% _self.admin_status(user) %}. You may also move it to a separate file, and use twig's import tag to gain access to it.

Creating a twig function is a better option, for details see extending twig. It boils down to creating a regular function, that may be called from twig, so code like this becomes possible:

{% if user_is_admin(user) %}

You'll also need to read enabling custom twig extensions.
