Bignum Tests: remove OperationCommonArchSplit

Browse Source 
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.
