Update for specialised closures (THUNK_n_p etc.)

Print total memory in use as part of -ghc-timing output.

- Add finalise#
- deRefWeak# becomes an inline primop.

- Add finalise#
- Add mkWeakNoFinaliser
- Move deRefWeak# from an out-of-line primop to an inline one.

Report actual amount of memory in use by the compiler in the
-Rghc-timing output.

Fix two bugs in formatRealFloat.

- Increase stack size for PrelPack.lhs

Clarification about the root set and top-level objects for the
reachability property.

H98 Prelude tweaks

A couple of underscore got lost a long time ago.

unwibble

Zh --> zh

zh --> Zh (for genSymZh and resetGenSymZh)

zh --> Zh

PrelInfo should define deRefStablePtr and friends to be in PrelStable

Zh --> zh

Add OccName.mkMethodOcc, whose absence broke nofib/spectral/fft2

- Be a bit more accurate about +RTS -H<size>, now we attempt to estimate
  the amount of memory that will be needed at the next GC based on
  the amount of promotion going on, and adjust the size of the allocation
  area appropriately.

- tidy up, move some stuff into Storage.c.

Fix erroneous name-clash report when a module ends up importing itself (eg TcEnv)

Remove unnecessary (and non-H98-friendly) import.

Update to match .hi-boot file.

Remove unprintable characters from module header.

Fix missing dash in SimplCore.lhs, which resulted in bogus specialisations

Several updates, mainly to the "heap objects" section.

Remove unnecessary imports

Changes for new z-encoding

Changes to PrelGHC.hi-boot for new z-encoding

Fix lost specialisations; a one-char change in Simplify.lhs

Always inline nullary constructors.  This makes a 
difference in:

	case x ># y of r {
	  True  -> f1 r
	  False -> f2 r
 	}

The code generator currently has difficulty binding "r"
to the boolean result of the comparision (and the compiler
crashes).  This fix substitutes for r, thus:

	case x ># y of r {
	  True  -> f1 True
	  False -> f2 False
 	}

Voila.

Increase CmdLineOpts stack size.

Undo bogus fix to CgCase.lhs

Use the +RTS -H<size> flag as a "suggestion" to the garbage collector
to use that much heap.  If you have plenty of memory, then saying
+RTS -H<large> will really help GC times.

Add RdrName.lhs

Haskell 98 updates

Finally!  This commits the ongoing saga of Simon's hygiene sweep

FUNCTIONALITY
~~~~~~~~~~~~~
a) The 'unused variable' warnings from the renamer work.  
b) Better error messages here and there, esp type checker
c) Fixities for Haskell 98 (maybe I'd done that before)
d) Lazy reporting of name clashes for Haskell 98 (ditto)

HYGIENE
~~~~~~~
a) type OccName has its own module.  OccNames are represented
   by a single FastString, not three as in the last round.  This
   string is held in Z-encoded form; a decoding function decodes
   for printing in user error messages.  There's a nice tight
   encoding for (,,,,,,,,,,,,,,,,,,,,,,,,,,,,,)

b) type Module is a proper ADT, in module OccName

c) type RdrName is a proper ADT, in its own module

d) type Name has a new, somwhat tidier, representation

e) much grunting in the renamer to get Provenances right.
   This makes error messages look better (no spurious qualifiers)

More missing files <sigh>

import PrelStable to get StablePtrs.

PrelForeign.StablePtr moved to PrelStable.

Add missing file.
