Although the alternative tokens `bitand` and `and` _can_ respectively be
used in place of `&` and `&&` for declarations, this is arguably misuse
of the tokens in contemporary programming. As of this commit, Clang will
warn—by default—when a programmer attempts to declare a name using
alternative tokens in place of reference symbols.

Depends on D107291 <https://reviews.llvm.org/D107291>.
