Major improvement to SpecConstr
This patch improves the SpecConstr pass, by
a) making it work with join points
b) making it generate specialisations transitively
As part of it, SpecConstr now carries a substitution with it, which
runs over the whole program as it goes. This turned out to be
a big win; simplified the implementation quite a bit.
I have *disabled* the specialisation on lambdas; it's pretty fragile,
and sometimes generates more and more specialisations. Something to
come back to, perhaps.
I rejigged the flag-handling a bit. Now the specification of passes
in DynFlags is a bit nicer; see
- optLevelFlags top-level data structure
- runWhen function
- CoreDoPasses constructor
There are now command-line flags
-fspec-constr
-fliberate-case
-fspec-threshold=N
which do the obvious thing. -O2 switches on both spec-constr and liberate-case.
You can use -fno-liberate-case, -fno-spec-constr after -O2 to switch them off again.
The spec-threshold applies to both these transformations; default value 200 for now.

Refactor the simplifier's treatment of case expressions
(NB: this patch could conceivably require some bits of the
following SpecConstr patch to compile cleanly. It's conceptually
independent, but I'm not 100% certain that I've included all
the necessary bits here.)
This patch cleans up the simplifier's handling of various
otimisations for case expressions, notably
- case elimination (discarding the case altogether)
- merging identical alternatives
- discarding impossible alternative
- merging nested cases
Previously this was partly handled before, and partly after,
simplifying the case alternatives. The trouble with that is
that the dead-ness information on the case binders gets munged
during simplification, and that turned out to mean that
case elmination essentially never happened -- stupid.
Now I've moved it all to before simplifying the alterntives.
In fact this reduces the amount of code, I think, and it's
certainly tidier. I don't think there is any loss.

Lightweight ticky-ticky profiling
The following changes restore ticky-ticky profiling to functionality
from its formerly bit-rotted state. Sort of. (It got bit-rotted as part
of the switch to the C-- back-end.)
The way that ticky-ticky is supposed to work is documented in Section 5.7
of the GHC manual (though the manual doesn't mention that it hasn't worked
since sometime around 6.0, alas). Changes from this are as follows (which
I'll document on the wiki):
* In the past, you had to build all of the libraries with way=t in order to
use ticky-ticky, because it entailed a different closure layout. No longer.
You still need to do make way=t in rts/ in order to build the ticky RTS,
but you should now be able to mix ticky and non-ticky modules.
* Some of the counters that worked in the past aren't implemented yet.
I was originally just trying to get entry counts to work, so those should
be correct. The list of counters was never documented in the first place,
so I hope it's not too much of a disaster that some don't appear anymore.
Someday, someone (perhaps me) should document all the counters and what
they do. For now, all of the counters are either accurate (or at least as
accurate as they always were), zero, or missing from the ticky profiling
report altogether.
This hasn't been particularly well-tested, but these changes shouldn't
affect anything except when compiling with -fticky-ticky (famous last
words...)
Implementation details:
I got rid of StgTicky.h, which in the past had the macros and declarations
for all of the ticky counters. Now, those macros are defined in Cmm.h.
StgTicky.h was still there for inclusion in C code. Now, any remaining C
code simply cannot call the ticky macros -- or rather, they do call those
macros, but from the perspective of C code, they're defined as no-ops.
(This shouldn't be too big a problem.)
I added a new file TickyCounter.h that has all the declarations for ticky
counters, as well as dummy macros for use in C code. Someday, these
declarations should really be automatically generated, since they need
to be kept consistent with the macros defined in Cmm.h.
Other changes include getting rid of the header that was getting added to
closures before, and getting rid of various code having to do with eager
blackholing and permanent indirections (the changes under compiler/
and rts/Updates.*).

Don't dump floated bindings just outside a lambda
We do not want the FloatOut pass to transform
f = \x. e
to
f = let lvl = ... in \x.e
The arity pinned on f isn't right any more; and see
Note [Floating out of RHSs].
Core Lint is now spotting the arity lossage (for a letrec), which is
how I spotted this bug.
I also re-jigged the code around floatBind; it's a bit tidier now.

Extend the local bindings at a breakpoint with one for the wrapped expression
By popular request, in a breakpoint it is possible now to inspect the result of the expression wrapped by the breakpoint.
The user interface for this is right now preliminar; there is a new binding called '_result' at every breakpoint. Suggestions are welcome!

Partial fix for #926
It seems that when a program exits with open DLLs on Windows, the
system attempts to shut down the DLLs, but it also terminates (some
of?) the running threads. The RTS isn't prepared for threads to die
unexpectedly, so it sits around waiting for its workers to finish.
This bites in two places: ShutdownIOManager() in the the unthreaded
RTS, and shutdownCapability() in the threaded RTS. So far I've
modified the latter to notice when worker threads have died
unexpectedly and continue shutting down. It seems a bit trickier to
fix the unthreaded RTS, so for now the workaround for #926 is to use
the threaded RTS.
