Reorganisation of the source tree
Most of the other users of the fptools build system have migrated to
Cabal, and with the move to darcs we can now flatten the source tree
without losing history, so here goes.

The main change is that the ghc/ subdir is gone, and most of what it
contained is now at the top level.  The build system now makes no
pretense at being multi-project, it is just the GHC build system.

No doubt this will break many things, and there will be a period of
instability while we fix the dependencies.  A straightforward build
should work, but I haven't yet fixed binary/source distributions.

More work thrown at HscMain.

MkIface.writeIfaceFile doesn't check GhcMode anymore. All it does
is what the name say: write an interface to disk.
I've refactored HscMain so the logic is easier to manage. That means
we can avoid running the simplifier when typechecking (: And best of
all, HscMain doesn't use GhcMode at all, anymore!

The new HscMain intro looks like this:

It's the task of the compilation proper to compile Haskell, hs-boot and
core files to either byte-code, hard-code (C, asm, Java, ect) or to
nothing at all (the module is still parsed and type-checked. This
feature is mostly used by IDE's and the likes).
Compilation can happen in either 'one-shot', 'batch', 'nothing',
or 'interactive' mode. 'One-shot' mode targets hard-code, 'batch' mode
targets hard-code, 'nothing' mode targets nothing and 'interactive' mode
targets byte-code.
The modes are kept separate because of their different types and meanings.
In 'one-shot' mode, we're only compiling a single file and can therefore
discard the new ModIface and ModDetails. This is also the reason it only
targets hard-code; compiling to byte-code or nothing doesn't make sense
when we discard the result.
'Batch' mode is like 'one-shot' except that we keep the resulting ModIface
and ModDetails. 'Batch' mode doesn't target byte-code since that require
us to return the newly compiled byte-code.
'Nothing' mode has exactly the same type as 'batch' mode but they're still
kept separate. This is because compiling to nothing is fairly special: We
don't output any interface files, we don't run the simplifier and we don't
generate any code.
'Interactive' mode is similar to 'batch' mode except that we return the
compiled byte-code together with the ModIface and ModDetails.
