Tilmann Scheller 9bd0d2a6a0 [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.
