      Add constructor CBytesPerWord to (the wildly-misnamed) CAddrMode, and
      use this in various places to remove word size dependencies in the
      C -> C simplification pass.  Tart up the Stix constant folder a bit
      so as to be able to fold out the shift/mask literal expressions.

      	Fix the instance-decl wart
      This commit implements the (proposed) H98 rule for
      resolving the class-method name in an instance decl.
      	module M( C( op1, op2 ) ) where
      		-- NB: op3 not exported
      	  class C a where
      	    op1, op2, op3 :: a -> a
      	module N where
      	  import qualified M as P( C )
      	  import qualified M as Q hiding( op2 )
      	  instance P.C Int where
      	    op1 x = x
      	    -- op2, op3 both illegal here
      The point is that
        a) only methods that can be named are legal
           in the instance decl
      	(so op2, op3 are not legal)
        b) but it doesn't matter *how* they can be named
      	(in this case Q.op1 is in scope, though
      	the class is called P.C)
      The AvailEnv carries the information about what's in scope,
      so we now have to carry it around in the monad, so that
      instance decl bindings can see it.  Quite simple really.
      Same deal for export lists. E.g.
      	module N( P.C( op1 ) ) where
      	  import qualified M as P( C )
      	  import qualified M as Q hiding( op2 )
      Actually this is what GHC has always implemented!

      package rts (mingw32): in installed mode, add gcc-lib/ to library_dirs,
      forcing it to be used by default. This allows other backend tools to be
      used (e.g., `dllwrap') without haphazardly mixing & matching (import)

              Translate out PrimOps at the AbstractC level
      This is the first in what might be a series of changes intended
      to make GHC less dependent on its C back end.  The main change is
      to translate PrimOps into vanilla abstract C inside the compiler,
      rather than having to duplicate that work in each code generation
      route.  The main changes are:
      * A new type, MachOp, in compiler/absCSyn/MachOp.hs.  A MachOp
        is a primitive operation which we can reasonably expect the
        native code generators to implement.  The set is quite small
        and unlikely to change much, if at all.
      * Translations from PrimOps to MachOps, at the end of
        absCSyn/AbsCUtils.  This should perhaps be moved to a different
        module, but it is hard to see how to do this without creating
        a circular dep between it and AbsCUtils.
      * The x86 insn selector has been updated to track these changes.  The
        sparc insn selector remains to be done.
      As a result of this, it is possible to compile much more code via the
      NCG than before.  Almost all the Prelude can be compiled with it.
      Currently it does not know how to do 64-bit code generation.  Once
      this is fixed, the entire Prelude should be compilable that way.
      I also took the opportunity to clean up the NCG infrastructure.
      The old Stix data type has been split into StixStmt (statements)
      and StixExpr (now denoting values only).  This removes a class
      of impossible constructions and clarifies the NCG.
      Still to do, in no particular order:
      * String and literal lifting, currently done in the NCG at the top
        of nativeGen/MachCode, should be done in the AbstractC flattener,
        for the benefit of all targets.
      * Further cleaning up of Stix assignments.
      * Remove word-size dependency from Abstract C.  (should be easy).
      * Translate out MagicIds in the AbsC -> Stix translation, not
        in the Stix constant folder. (!)
      Testsuite failures caused by this:
      * memo001 - fails (segfaults) for some unknown reason now.
      * arith003 - wrong answer in gcdInt boundary cases.
      * arith011 - wrong answer for shifts >= word size.
      * cg044 - wrong answer for some FP boundary cases.
      These should be fixed, but I don't think they are mission-critical for

      consistent with the repo contents. (wouldn't surprise me
      if there's coreSyn/Subst.lhs change that hasn't been
      committed yet...)

      Dont fall over on data T deriving(Show)

      	Fix a tiresome and longstanding bug
      	in typechecking of unlifted bindings
      	data T = MkT Int# Int#
      	f :: T -> Int#
      	f t = a +# b
      	      MkT a b = if ... then t else t
      This should really be OK, but if the "..." includes
      some constraints, the constraint simplifier was trying to
      generate some d1=d2 bindings. This is Bad because the desugarer
      treats unlifted bindings very specially (they are strict).
      This commit fixes the problem, by ensuring we never get
      local dictionary binding for an unlifted group.
      This fixes the bug which has been making the Alpha port fall
      over with a pattern-match failure in DsExpr.  Nothing to do
      with Alpha; it's just that the word-size change gave rise
      to a little more commoning-up of literals in the type checker
      which in turn made the desugarer it fall over.

      Hmmm, we probably should install HsStd.h, too. PackageSrc.hs mentions
      it, and "make boot" in ghc/utils/hsc2hs fails without it. Perhaps this
      should be fixed differently, but I can't figure out how to do this
