Make NestedNumberAsFloat64 accuracy test architecture-neutral.

NestedNumberAsFloat64 will convert int64s to float64 only if the int64 value can be represented
exactly by a float64. The original test for this property used a roundtrip conversion from int64 to
float64 and back, and the behavior of these conversions is inconsistent across architectures.
