Gilles Peskine 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).

Gilles Peskine 6d40e54db0 Split the high nesting of BignumModRawConvertRep.generate_function_tests
Pylint complains about the nesting. It's not wrong.

No behavior change.

Minos Galanakis 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.

Minos Galanakis 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:
    symbol = ""
    input_style = "arch_split"
    arity = 1

Gilles Peskine ad335b55ff Fix representation conversion with 32-bit limbs
The Montgomery representation depends on the limb size. So the
representation conversion test cases need separate 64-bit and 32-bit cases
when the representation is Montgomery.
