Add -fmono-pat-binds, and make it the default
In Haskell 98, pattern bindings are generalised. Thus in
(f,g) = (\x->x, \y->y)
both f and g will get polymorphic types. I have become convinced
that generalisation for pattern-bound variables is just a bridge
toof far. It is (I claim) almost never needed, and it adds significant
complication. (All the more so if we add bang patterns.)
So the flag -fmono-pat-binds switches off generalisation for pattern
bindings. (A single variable is treated as a degnerate funtction
binding.)
Furthremore, as an experiment, I'm making it the default. I want
to see how many progarms fail with monomorphic pattern bindings.
You can recover the standard behaviour with -fno-mono-pa-binds.

Fix RULES lossage
Don Stewart and Duncan Coutts encountered the following situation.
f = <rhs>
{-# RULES f ... #-}
where f is not exported, but appears in the inlinings of other
functions that are exported. Then what happened was that the desugarer
produced this:
M.f = f
f = <rhs>
where the rules get attached to the M.f. But since M.f's RHS is trivial
(just f) it was unconditionally inlinined at all its call sites,
thereby losing the RULES attached to it.
This *is* a fragile aspect of rules. However this fix solves the
problem by instead generating
f = M.f
M.f = <rhs>
A pretty small chanage to the desugarer does the job. It still feels
a little fragile, bt it's certainly more robust than before.

Experimental flag -fdicts-cheap
This experimental flag, -fdicts-cheap, makes a let-binding that bind a
value of dictionary type look cheap. That in turn leads to more
eta expansion. Instead of
f = /\a. \(d1:Ord a). let d2:Ord [a] = dfOrd a d1 in
\(x:a). <stuff>
which has arity 1, you get
f = /\a. \(d1:Ord a). \(x:a).
let d2:Ord [a] = dfOrd a d1 in <stuff>
Now f has arity 2.
This can cretainly waste dictionary-construction work, if f is
partially applied to its dictionary argument. However it has knock-on
effects. Because f has arity 2, we won't float (f Int d) out of
\x. h (f Int d)
Floating f out of this lambda makes it impossible for an h/f fusion
rule to fire; and this unexpected loss of RULE application was the
immediate reason for implementing this flag. (Roman Leshchinskiy came
across this when working on array fusion.)
I've implemented the change only in CoreUtils.arityType, which
only affects eta expansion. I thought of putting the change in
exprIsCheap, which is a more systematic place (the former calls
the latter) but
a) I wanted this under flag control, and the flags
are not readily available to all callers of exprIsCheap
b) I'm not 100% convinced that this change is a good
idea, so it's reasonable to do the narrowest change
that solves the immediate problem.

Add %local-tag to external core output
Hello, this is my first patch contributed to GHC. If there are any
inadequacies about it (maybe like this introductory disclaimer), please
let me know about it.
So, the need for this patch arose, while I was involved with processing
hcr files (external core output) and I noticed, that the output didn't
fully conform to the specification [1].
No %local-tags were used, which turned out to be a real nuisance as it
was not possible to determine which VDEFs can be erased in a further
optimization process and which ones are exported by the module.
Since the specification does not define the meaning of the %local-tag, I
assume, it makes sense, that it tags all functions, that are not
exported by the module.
The patch does not fully comply to the specification, as in my
implementation a local tag may appear before a VDEF but not before a
VDEFG.

fix possible ^C problems
Calling prodAllCapabilities() from interruptStgRts() was wrong, for
the same reasons that we stopped doing it in handle_tick(). We now
use the same mechanism (send a byte down the pipe to the IO manager
thread), but abstract it in a wakeUpRts() function in the scheduler.

New tracing interface
A simple interface for generating trace messages with timestamps and
thread IDs attached to them. Most debugging output goes through this
interface now, so it is straightforward to get timestamped debugging
traces with +RTS -vt. Also, we plan to use this to generate
parallelism profiles from the trace output.

Make it so that StgWord/StgInt are longs
This means we can use a %ld format specifier for StgWord/StgInt with
printf and not get shouted at by gcc.

Add new RTS flags for tracing:
-vs Trace scheduler events (see also -Ds with -debug)
-vt Time-stamp trace messages
the intention is that we will pipe the -vs output into a
profile-generating tool. This commit includes the flags only,
functionality to follow.
