  -----------
  [FuncSpec] Allow ConstExprs that are function pointers

This is a follow up of D110529 that disallowed constexprs. That change
introduced a regression as this also disallowed constexprs that are function
pointers, which is actually one of the motivating use cases that we do want to
support.
