Subject: Alternate fix to PR12248:  put Sema in charge of special-casing the
 diagnostic for assigning to a copied block capture.  This has the pleasant
 side-effect of letting us special-case the diagnostic for assigning to a
 copied lambda capture as well, without introducing a new non-modifiable
 enumerator for it.
