  Usage verification changes / ticky-ticky changes:

  We want to verify that SingleEntry thunks are indeed entered at most
  once.  In order to do this, -ticky / -DTICKY_TICKY turns on eager
  blackholing.  We blackhole with new blackholes: SE_BLACKHOLE and
  SE_CAF_BLACKHOLE.  We will enter one of these if we attempt to enter
  a SingleEntry thunk twice.  Note that CAFs are dealt with in by
  codeGen, and ordinary thunks by the RTS.

  We also want to see how many times we enter each Updatable thunk.
  To this end, we have modified -ticky.  When -ticky is on, we update
  with a permanent indirection, and arrange that when we enter a
  permanent indirection we count the entry and then convert the
  indirection to a normal indirection.  This gives us a means of
  counting the number of thunks entered again after the first entry.
  Obviously this screws up profiling, and so you can't build a ticky
  and profiling compiler any more.

  Also a few other changes that didn't make it into the previous 8
  commits, but form a part of this set.

Move 4.01 onto the main trunk.

syslibs: generate dependencies on Prelude modules

remove references to hslibs, and add \$Id\$

remove spurious reference to GHC.hi (probably a cut-and-paste-o).

Library re-organisation:

All libraries now live under ghc/lib, which has the following structure:

	ghc/lib/std    		--  all prelude files 		(libHS.a)
	ghc/lib/std/cbits

	ghc/lib/exts		-- standard Hugs/GHC extensions (libHSexts.a)
				-- available with '-fglasgow-exts'

	ghc/lib/posix		-- POSIX library                (libHSposix.a)
	ghc/lib/posix/cbits     -- available with '-syslib posix'

	ghc/lib/misc		-- used to be hslibs/ghc	(libHSmisc.a)
	ghc/lib/misc/cbits	-- available with '-syslib misc'

	ghc/lib/concurrent	-- Concurrent libraries		(libHSconc.a)
				-- available with '-concurrent'

Also, several non-standard prelude modules had their names changed to begin
with 'Prel' to reduce namespace pollution.

	Addr      ==> PrelAddr     (Addr interface available in 'exts')
	ArrBase   ==> PrelArr
	CCall     ==> PrelCCall    (CCall interface available in 'exts')
	ConcBase  ==> PrelConc
	GHCerr    ==> PrelErr
	Foreign   ==> PrelForeign  (Foreign interface available in 'exts')
	GHC       ==> PrelGHC
	IOHandle  ==> PrelHandle
	IOBase    ==> PrelIOBase
	GHCmain   ==> PrelMain
	STBase    ==> PrelST
	Unsafe    ==> PrelUnsafe
	UnsafeST  ==> PrelUnsafeST
