@wenshao After offline discussion with @kevinb9n, we think we should add
another sentence in the API specification:
This is identical to {@link #loadConstant(ConstantDesc)
loadConstant(Integer.valueOf(value))}.
And repeat this for long, float, and double versions (with
`Long.valueOf(value)` etc.)
This avoids confusions around this API.
