26439bf692 Revert "Add dependency for generated test cases"
The 'MBEDTLS_TEST_HOOKS' belongs to a test function and
not to a test case.

This reverts commit 1e8c210b9d.

aaa1d2a276 Move the quasi reduction fixing function to bignum_mod_raw
Rename the function to 'fix_quasi_reduction' to better suite its functionality.
Also changed the name prefix to suite for the new module.

5efe449a6a More robust dependency filtering
Only remove the MBEDTLS_HAVE_INTnn dependency, not any other dependency that
might be present.

No behavior change, this is just robustness.

f287366376 Simplify logic and document test_cases_for_values
Explain what's going on in BignumModRawConvertRep.test_case_for_values.

Simplify the logic and the interdependencies related to limb sizes:
* Montgomery is the special case, so base the decisions on it.
* As soon as we've encountered one limb size, no matter what it is,
  give up.

No behavior change, other than changing the numbering of test cases (which
previously included more skipped test cases).

342b9a903d bignum_mod_raw.py: Added a filtering logic to BignumModRawConvertRep.generate_function_tests()
This patch introduces a hybrid approach to input_styles, and will remove the
dependency requirements from test cases with `ModulusRepresentation.OPT_RED`

As a result it is reducing testing input duplication.

ae4d2cf3e3 bignum_common.py: Introduce the set_representation setter.
This patch adds the default representation attribute through a
setter() method in `BignumModRawConvertRep()`

It also adds standard common template properties:

    input_style = "arch_split"
    arity = 1

ad335b55ff Fix representation conversion with 32-bit limbs
The Montgomery representation depends on the limb size. So the

when the representation is Montgomery.

Before arg_ attributes were the arguments as they were defined in the

and more consistent.

This change makes the hex_ properties redundant and therefore they are
removed.

of appearance of 64 and 32 bit mpi_core_add_and_add_if test cases has

and the order of the 64 and 32 bit versions have been swapped.

0cd8967ba1 Split test generator base class
The class BaseTarget served two purposes:
- track test cases and target files for generation
- provide an abstract base class for individual test groups

Splitting these allows decoupling these two and to have further common
