Since adding MO_ATOM_MASK, the maximum MemOpIdx requires 15 bits, which overflows the 12 bit field allocated for TCI memory ops. Expand the field to 16 bits for 2-operand memory ops, and place the value in TCG_REG_TMP for 3-operand memory ops (same as we already do for 4-operand memory ops). Cures a debug assert for aarch64, with FEAT_LSE enabled.
