This commit fixes code generation for loading halfwords using an offset greater than 255. The old code blindly encoded the offset into a `LDRH Rd, [Rn, #imm]` opcode, but only the lowest 8 bits would be put into the opcode itself. This commit instead generates a two-opcodes sequence, a constant load into R8, and then `LDRH Rd, [Rn, R8]`. This fixes `tests/extmod/vfs_rom.py` for the qemu/SABRELITE board.
