[ARM] Make the assembler reject unpredictable pre/post-indexed ARM LDRH/LDRSH instructions.

The ARM ARM prohibits LDRH/LDRSH instructions with writeback into the source register. With this commit this constraint is now enforced and we stop assembling LDRH/LDRSH instructions with unpredictable behavior.
