CanInline

The invocation of the primitive can be safely inlined. In particular, it simply computes a value or changes the state of something and does not replace the current continuation in unusual ways. Thus, something more specific than a general invocation can be embedded in the calling L2Chunk. Since code for potential reification is still needed in the failure case, this flag is less useful than it used to be when a continuation had to be reified on every non-primitive call.
