--------------------
	A major hygiene pass
	--------------------

1. The main change here is to

	Move what was the "IdFlavour" out of IdInfo,
	and into the varDetails field of a Var

   It was a mess before, because the flavour was a permanent attribute
   of an Id, whereas the rest of the IdInfo was ephemeral.  It's
   all much tidier now.

   Main places to look:

	   Var.lhs	Defn of VarDetails
	   IdInfo.lhs	Defn of GlobalIdDetails

   The main remaining infelicity is that SpecPragmaIds are right down
   in Var.lhs, which seems unduly built-in for such an ephemeral thing.
   But that is no worse than before.


2. Tidy up the HscMain story a little.  Move mkModDetails from MkIface
   into CoreTidy (where it belongs more nicely)

   This was partly forced by (1) above, because I didn't want to make
   DictFun Ids into a separate kind of Id (which is how it was before).
   Not having them separate means we have to keep a list of them right
   through, rather than pull them out of the bindings at the end.

3. Add NameEnv as a separate module (to join NameSet).

4. Remove unnecessary {-# SOURCE #-} imports from FieldLabel.
