91a2aabb86 Refactor mpi_core_sub tests to use arch_split
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

4c59d35e00 Bignum tests: make args use input_style
Before arg_ attributes were the arguments as they were defined in the
python script. Turning these into properties and having them take the
form respect the style set in input_style makes the class easier to use
and more consistent.

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

There are no semantic changes to the generated test cases. (The order
of appearance of 64 and 32 bit mpi_core_add_and_add_if test cases has
changed.)

6fa3f0653a Bignum Tests: remove OperationCommonArchSplit
The ArchSplit functionality was duplicated and moved to OperationCommon
from the other copy. The remnants of the functionality is moved to the
only subclass using this.

There is no semantic change to the generated tests. The order has
changed however: core_add tests have been moved before core_mla tests
and the order of the 64 and 32 bit versions have been swapped.

3aeb60add6 Bignum test: move archsplit to superclass
We need arch split tests in different modules, moving it to the common
module makes it reusable.

No intended changes in the generated tests. (The position of the
core_add_if tests changed, but they are still all there.)

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
superclasses across targets.

No intended change in generated test cases.

5933f691a2 Add merge slots to Bignum files
Legacy Bignum is excluded as it doesn't get regular extensions like new
ones.

Each slot uses comments of their respective filetype. Since .data files
don't have a syntax for comments, dummy test cases are used. (These test
cases will never be executed and no noise will be added to tests.)

dd2e4683d0 Bignum Core: add limb size specific test generation
In Bignum Core the result also involves a carry and both the result and
the carry depend on the size of the limbs.

Before this change both 32 and 64 bit specific result have been passed
to the test functions.

Moving this decision out of the tests makes the test functions easier to
write and read and the test cases easier to read and debug. The change
doesn't make writing the generator script any harder and might even make
reading it easier.
