91a2aabb86 Refactor mpi_core_sub tests to use arch_split

dac44e6021 Bignum tests: add default datasets 
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.

b2a850c746 Bignum Tests: add test data 
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.
