  -----------
  Diagnose use of _Noreturn on a struct/union field

C99 6.7.4p2 clarifies that a function specifier can only be used in the
declaration of a function. _Noreturn is a function specifier, so it is
a constraint violation to write it on a structure or union field, but
we missed that case.

Fixes #56800
