We were always setting the block alignment to 2 bytes in Thumb mode
and 4-bytes in ARM mode, but this could cause reducing the block
alignment when it already had been aligned (e.g. in Thumb mode when
the block is a CPE that was already 4-byte aligned).

      

Patch by Momchil Velikov, I've only added a test.
