The primitive overloads of `loadConstant` avoid extraneous boxing. 👍

I think we need to rearrange this to follow the code style, like:
if (value instanceof Number) {
if (value instanceof Integer i)
return loadConstant(i);
if (value instanceof Long l)
return loadConstant(l);
if (value instanceof Float f)
return loadConstant(f);
if (value instanceof Double d)
return loadConstant(d);
}
if (value == null || value == ConstantDescs.NULL)
return aconst_null();
return ldc(value);

These are technically since 24.
