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.

ad335b55ff Fix representation conversion with 32-bit limbs
