Research direction

Edit xml/System.Reflection.Emit/OpCodes.xml, locating the documentation entry for the IL cpblk instruction. Read the linked CoreCLR proposal for the intended wording, then update the remarks to state that the memory must be blittable and cannot contain GC handles. Done means the generated OpCodes.Cpblk documentation accurately includes this restriction.
