So far the only tests we had were end to end tests to assess the
functionality of simple programs and, in particular, certain helper
functions. In the perspective of being able to test individual features,
and in particular check that we have no regressions in our analyses, we
isolated these end to end tests in the Runtime directory. We kept in the
root test directory the mechanism to compile a binary for a certain
architecture so that all the test types can use it.
