This is a 1-line patch (with a TODO for AVX because that will affect even more regression tests) that lets us substitute the appropriate 64-bit store for the float/double/int domains. It's not clear to me exactly what the difference is between the 0xD6 (MOVPQI2QImr) and 0x7E (MOVSDto64mr) opcodes, but this is apparently the right choice.
