[ARM] Another f16 litpool fix
We were always setting the block alignment to 2 bytes in Thumb mode
and 4-bytes in ARM mode (r325754, and r325012), 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.
