    Switch from Maybe TyCon to a richer type for promotion

      The new type distinguishes the two cases where promotion isn't possible:
    1) Promotion isn't possible, as it's disabled by a 'data type' declaration
    2) Promotion isn't possible because we don't know how to promote it

    Thread data kind syntax through the interface

      Things are not quite right at the moment.  The issue is that we can't
    distinguish abstract types from types that are constructors in a data kind.
    As such, we should introduce a new constructor to TyCon to help
    disambiguate these two cases.  Also it might be nice to add a new TyCon
    for kinds, which would avoid the need for a new RHS in the AlgTyCon case.

    Implement the 'data type' syntax and checking

      Add a new form of data declaration where the 'type' modifier can be used
    to prevent data promotion.  For example

      data type T = K

    will not yield a promoted kind T, and promoted type K, even though they are
    in principle promotable.

When servicing a stack overflows, only throw an exception to the given
thread if the user explicitly set a max stack size, using +RTS -K.
Otherwise just service it normally and grow the stack.

In case we actually run out of *heap* (stack chuncks are allocated on
the heap), then we need to bail by calling the stackOverflow() hook and
exit immediately.

This patch encompasses most of the basic infrastructure for GHCJS. It
includes:

  * A new extension, -XJavaScriptFFI
  * A new architecture, ArchJavaScript
  * Parser and lexer support for 'foreign import javascript', only
    available under -XJavaScriptFFI, using ArchJavaScript.
  * As a knock-on, there is also a new 'WayCustom' constructor in
    DynFlags, so clients of the GHC API can add custom 'tags' to their
    built files. This should be useful for other users as well.

The remaining changes are really just the resulting fallout, making sure
all the cases are handled appropriately for DynFlags and Platform.

Under --slow, the DPH tests can take incredible amounts of time to run.
And on some platforms, we may not have a fully working linker in order
to build DPH etc anyway. So this provides a way to turn it off.

This flag is off by default, but should your specify it, you can skip
the required 'dph' libraries in a build, should you remove them from the
source tree.

Parser.hs needs to be compiled with -fcmm-sink on x86 platforms, so the
register allocator doesn't run out of stack slots. Previously, we had to
do some CPP hacks in order to emit an #ifdef into the file - this is
because we preprocess it once up front, and run the preprocessor again
when we compile it.

There's two cases: the boostrap compiler is > 7.8, and the stage1 parser
needs the flag, or the stage1 compiler is compiling the stage2
Parser.hs, and needs the flag..

The previous approach was super fragile with Clang. The more principled
fix is to instead do this through the build system.

This fixes #8182.

And update comments

When inferring roles it is Much More Kosher to work on the source
type, as written by the user, rather than the representation type as
computed by GHC.  Error messages may be better and, more subtly, the
representation type is the result of a pretty complicated calculation
and I'm worried about accidental cycles.

Now that IfBangs can contain coercions, which can mention the
very type being typechecked, the tc_strict call must be inside
forkM. This led to Trac #8221

This bug meant that we tried to unpack Link in

  data Link a = MkLink !(Link a)

when -funbox-small-strict-fields was on.  See Trac #8221.

We have various problems with reallocating the array of Capabilities,
due to threads in waitForReturnCapability that are already holding a
pointer to a Capability.

Rather than add more locking to make this safer, I decided it would be
easier to ensure that we never move the Capabilities at all.  The
capabilities array is now an array of pointers to Capabaility.  There
are extra indirections, but it rarely matters - we don't often access
Capabilities via the array, normally we already have a pointer to
one.  I ran the parallel benchmarks and didn't see any difference.

For some reason, the new `GccIsClang` variable introduced via
fc4856f9 for addressing #8148
isn't set explicitly to `NO`; so this simply changes the test
`ifeq $(GccIsClang) NO` to `ifneq $(GccIsClang) YES` which
should fix the build with and w/o Clang.

* This partially fixes #8148. However, --with-ghc-4.8 will still not work given the rather dubious m4 macros and the failures in the test suite due to '-nodefaultlibs' still need to be fixed.

The original problem was that we weren't bringing varaibles bound in the
interactive context into scope before Linting the result of a top-level
declaration in GHCi.  (We were doing this for expressions.)

Moreover I found that we weren't Linting the result of desugaring
a GHCi expression, which we really should be doing.

It took me a bit of time to unravel all this, and I did some refactoring
to make it easier next time.

  * CoreMonad contains the Lint wrappers that get the right
    environments into place.  It always had endPass and lintPassResult
    (which Lints bindings), but now it has lintInteractiveExpr.

  * Both use a common function CoreMonad.interactiveInScope to find
    those in-scope variables.

Quite a bit of knock-on effects from this, but nothing exciting.

Fixing #8217 for the unix(-like) case.
