Fix bogus worker for newtypes

The "worker" for a newtype is actually a function
with a small (compulsory) unfolding, namely a cast.

But the construction of this function was plain wrong
for newtype /instances/; it cast the arguemnt to the
family type rather than the representation type.

This never actually bit us because, in the case of a
family instance, we immediately cast the result to
the family type.  So we get
   \x. (x |> co1) |> co2

where the compositio of co1 and co2 is ill-kinded.
However the optimiser (even the simple optimiser)
just collapsed those casts, ignoring the mis-match
in the middle, so we never saw the problem.

Trac #16191 is indeed a dup of #16141; but the resaon
these tickets produce Lint errors is not the unnecessary
forcing; it's because of the ill-typed casts.

This patch fixes the ill-typed casts, properly.  I can't
see a way to trigger an actual failure prior to this
patch, but it's still wrong wrong wrong to have ill-typed
casts, so better to get rid of them.

and  5aa29231ab7603537284eff5e4caff3a73dba6d2.

Obtaining a `DynFlags` is difficult, making using the lexer/parser
for pure parsing/lexing unreasonably difficult, even with `mkPStatePure`.
This is despite the fact that we only really need

    * language extension flags
    * warning flags
    * a handful of boolean options

The new `mkParserFlags'` function makes is easier to directly construct a
`ParserFlags`. Furthermore, since `pExtsBitmap` is just a footgun, I've gone
ahead and made `ParserFlags` an abstract type.

Also, we now export `ExtBits` and `getBit` instead of defining/exporting a
bunch of boilerplate functions that test for a particular 'ExtBits'.
In the process, I also

  * cleaned up an unneeded special case for `ITstatic`
  * made `UsePosPrags` another variant of `ExtBits`

Fix tests for `integer-simple`

small integers directly into applications of `S#`.

as many tests as possible to use `Int`.

Ryan Scott [Thu, 10 Jan 2019 21:55:51 +0000 (16:55 -0500)] 
Control validity-checking of type synonym applications more carefully

Trac #16059 shows that when validity checking applications of type
synonyms, GHC sometimes wasn't checking the expanded type enough.
We must be careful, however, since checking both the expanded type as
well as the arguments to the type synonym can lead to exponential
blowup (see https://ghc.haskell.org/trac/ghc/ticket/16059#comment:4).
Nor can we omit checking either the expanded type or the argument for
correctness reasons.

The solution here is to introduce a new `ExpandMode` data type that
is plumbed through all of the type-validity-checking functions in
`TcValidity`. `ExpandMode` dictates whether we only check the
expanded type (`Expand`), only check the arguments (`NoExpand), or
both (`Both`). Importantly, if we check `Both` in the function for
validity checking type synonym applications, then we switch to
`NoExpand` when checking the arguments so as to avoid exponential
blowup. See `Note [Correctness and performance of type synonym validity
checking]` for the full story.
