Make dataToQa aware of Data instances which use functions to implement toConstr
Trac #10796 exposes a way to make `template-haskell`'s `dataToQa` function
freak out if using a `Data` instance that produces a `Constr` (by means of
`toConstr`) using a function name instead of a data constructor name. While
such `Data` instances are somewhat questionable, they are nevertheless present
in popular libraries (e.g., `containers`), so we can at least make `dataToQa`
aware of their existence.
In order to properly distinguish strings which represent variables (as opposed
to data constructors), it was necessary to move functionality from `Lexeme` (in
`ghc`) to `GHC.Lexeme` in a new `ghc-boot` library (which was previously named
`bin-package-db`).
