Now that we have auto packages, it makes sense to keep all the
interfaces for hierarchical libraries in the same directory tree.  So
now, instead of putting interfaces for package P in $libdir/imports/P,
we put them all in $libdir/imports.

Interfaces for old non-auto non-hierarchical packages now go in
$libdir/hslibs-imports/P for package P.

Change the way SRTs are represented:

Previously, the SRT associated with a function or thunk would be a
sub-list of the enclosing top-level function's SRT.  But this approach
can lead to lots of duplication: if a CAF is referenced in several
different thunks, then it may appear several times in the SRT.
Let-no-escapes compound the problem, because the occurrence of a
let-no-escape-bound variable would expand to all the CAFs referred to
by the let-no-escape.

The new way is to describe the SRT associated with a function or thunk
as a (pointer+offset,bitmap) pair, where the pointer+offset points
into some SRT table (the enclosing function's SRT), and the bitmap
indicates which entries in this table are "live" for this closure.
The bitmap is stored in the 16 bits previously used for the length
field, but this rarely overflows.  When it does overflow, we store the
bitmap externally in a new "SRT descriptor".

Now the enclosing SRT can be a set, hence eliminating the duplicates.

Also, we now have one SRT per top-level function in a recursive group,
where previously we used to have one SRT for the whole group.  This
helps keep the size of SRTs down.

Bottom line: very little difference most of the time.  GHC itself got
slightly smaller.  One bad case of a module in GHC which had a huge
SRT has gone away.

While I was in the area:

  - Several parts of the back-end require bitmaps.  Functions for
    creating bitmaps are now centralised in the Bitmap module.

  - We were trying to be independent of word-size in a couple of
    places in the back end, but we've now abandoned that strategy so I
    simplified things a bit.

 Use the Infer/Check idea for typechecking higher-rank types
----------------------------------

The main idea is that

data Expected ty = Infer (TcRef ty) | Check ty

tcMonoExpr :: Expr -> Expected TcRhoType -> TcM Expra

This "Expected" type tells tcMonoExpr whether it's doing inference or
checking.  It replaces the "HoleTv" flavour of type variable.

This actually leads to slightly more lines of code, but it's much
clearer, and the new type distinctions showed up several subtle bugs
in the previous implementation.  It all arose out of writing the
prototype implementation for the paper.

Error messages wibble around a little bit.  I'm not quite certain why!  But the
changes look like improvements to me.

Consider the stupid definition

f = \x -> f x

We were erroneously eta-reducing this to

f = f

(unsound because they'd be distinguishable by `seq`)

The reason was that simplLazyBind was exposing the arity of
a recursive function to its own RHS, when all it was really
trying to do was expose the *rules* for the function.

Easily fixed.   This fixes some

"Bad eta expand"

warnings.  Good all round.  In particular, fixes rn006.
