If HOSTCC is set, use that to generate files, otherwise use CC. This
should make cross-compilation with generated files slightly easier.

The 'MBEDTLS_TEST_HOOKS' belongs to a test function and
not to a test case.

This prevents a return type error in a later function that uses the
dictionaries here properly typed.

Rename the function to 'fix_quasi_reduction' to better suite its functionality.
Also changed the name prefix to suite for the new module.

Only remove the MBEDTLS_HAVE_INTnn dependency, not any other dependency that
might be present.
No behavior change, this is just robustness.

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).

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.

This patch adjusts the test generating method to calculate all possible combinations for

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

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.

With the default input style (which is "variable"), fill all bignum test

Tests are refactored to generate separate cases for 32-bit and 64-bit
limbs using arch_split. Duplicate arguments and branching in the test
function is removed.

Normally we need all the combinations, unique combinations make sense

Remove old dataset that was overriding the defaults in bignum_core. This

Add data for small values, 192 bit and 1024 bit values, primes,
non-primes odd, even, and some typical corner cases.
All subclasses override this for the time being so there are no changes
to the test cases.

The goal of this commit is to add some constants that can be used to
define datasets and add test data in a more readable and reusable
manner.
All platforms using ECC need to support calculations with at least 192
bits, therefore constants for this length are added. We are not using a
curve prime as those will be tested elsewhere and it is better not to
play favourites.
All platforms using RSA or FFDH need to support calculations with at
least 1024 bits, therefore numbers of this size are added too.
A safe prime is added for both sizes as it makes all elements generators
(except 0 and 1 of course), which in turn makes some tests more
effective.
