      Fix 64-bit shift operations.
      - Move the declarations of the 64-bit "primops" from PrimOps.h to
        HsBase.h where they more properly belong.
      - change the names of the 64-bit shift ops to include the "unchecked"
      - add checked versions of these primops to GHC.Int and GHC.Word, and
        use them.
      - update the FFI declarations in GHC.Int and GHC.Word while I'm there.

      No need to compile Printf.lhs with -fvia-c now.

      The foreign declaration for snprintf was wrong, because we need to
      give the type of the C function after applying C's type promotion
      rules.  Hence the Float argument should be a Double, because it
      occurs in the vararg section of the function type.

      Back out previous fix, it was wrong.

      Misc cleanup: remove the iface pretty-printing style, and clean up
      bits of StringBuffer that aren't required any more.

      Remove the interface file parser, and move .hi-boot parsing into the
      main parser.  The syntax of .hi-boot files is now greatly improved in
      terms of readability; here's an example:
      	module M where
      	data T
      	f :: T -> GHC.Base.Int
      note that
      	(a) layout can be used
      	(b) there's no explcit export list; everything declared
      	    is implicitly exported
      	(c) Z-encoding of names is no longer required
      	(d) Any identifier not declared in the current module must
      	    still be quailified with the module which originally
      	    defined it (eg. GHC.Base.Int above).
      We'd like to relax (d), but that will come later.

      		GlobalName --> ExternalName
      		LocalName  ->  InternalName
      For a long time there's been terminological confusion between
      	GlobalName vs LocalName	 (property of a Name)
      	GlobalId vs LocalId	 (property of an Id)
      I've now changed the terminology for Name to be
      	ExternalName vs InternalName
      I've also added quite a bit of documentation in the Commentary.

      Fix a bug in the native code generator's handling of floating-point
      arguments to ccalls: it wasn't correctly promoting float arguments to
      doubles.  Amazingly this has gone undetected for quite a while.
      Fixes bug #523996.

      Forced commit: note that the previous revision also improved the error
      message for a compiler stack overflow slightly.

      eek!  Somehow, I managed to make -fvia-C the default on the HEAD and
      nobody noticed for two months.

      	Fix a type-invariant bug
      We need to call Type.mkGenTyConApp from Type.mkAppTy, in
      case there's a partially applied type synonym.  Explanation
      with Type.mkAppTy.  All part of GHC's rather liberal treatment
      of type synonyms.
      Shown up by a program from Ralf Laemmel:
      	type Generic i o = forall x. i x -> o x
      	type Id x = x
      	comb :: Generic Id Id
      Test is typecheck/should_compile/tc149.hs

      Add a magic number to the beginning of interface files (0x1face :-) to
      avoid trying to read old text-style interfaces as binary (the usual
      result is an attempt to allocate a ByteArray larger than the available
      memory size and an obscure crash).

      If we are in a deadlock situation but there are signal handlers
      installed, pause() instead of reporting deadlock.  One of the signal
      handlers may allow the process to continue after being triggered.
      Fixes bug #525772.
      I've made a half-hearted attempt to clean up the deadlock code in the
      scheduler, it now looks slightly better.
