misaligned_operand instead of aligned_operand is used since
aligned_operand has
/* All patterns using aligned_operand on memory operands ends up
in promoting memory operand to 64bit and thus causing memory mismatch. */
if (TARGET_MEMORY_MISMATCH_STALL && !optimize_insn_for_size_p ())
return false;
which isn't true for *movqi_internal.
