Boolean littleEndian argument coerced in ToBoolean

24.2.4.14 DataView.prototype.setFloat64 ( byteOffset, value [ , littleEndian ] )
1. Let v be the this value.
2. If littleEndian is not present, let littleEndian be false.
3. Return ? SetViewValue(v, byteOffset, littleEndian, "Float64", value).
24.2.1.2 SetViewValue ( view, requestIndex, isLittleEndian, type, value )
...
15. Let bufferIndex be getIndex + viewOffset.
16. Return SetValueInBuffer(buffer, bufferIndex, type, numberValue, isLittleEndian).
24.1.1.6 SetValueInBuffer ( arrayBuffer, byteIndex, type, value [ , isLittleEndian ] )
...
9. Else if type is "Float64", then
a. Set rawBytes to a List containing the 8 bytes that are the IEEE 754-2008
binary64 format encoding of value. If isLittleEndian is false, the bytes are
arranged in big endian order. Otherwise, the bytes are arranged in little
endian order. [...]
