Beginnings of a Win32 merge.
... rearrange the build scripts to use input from files rather
than <<HERE documents.
... (no other changes; just working to get the meaty changes
isolated from the fluff)

Make EQUAL faster (about 50% improvement for short lists on x86-64).
As amazing as it might seem, there are actually real-world
applications where significant time is spent in EQUAL.

* Inline EQL in EQUAL
* Rearrange things a bit to enable the inlining
* Rewrite EQUAL to use a local helper function

* add (EQL LAMBDA-VAR LAMBDA-VAR) constraints on BIND and CSET
* add cast and test constraints to all eql lambda vars
* calculate the intersection of two lambda-var types when
encountering (IF (EQL X Y) ...) and neither X or Y is a subtype of
the other
* there is now only one invocation of FIND-AND-PROPAGATE-CONSTRAINTS
* since GEN depends on IN there is no COMPUTE-BLOCK-OUT shortcut
anymore, a full FIND-CONSTRAINTS-IN-BLOCK is done
* for blocks whose constraints won't be recalculated after the
prepass (see LEADING-COMPONENT-BLOCKS) do what
USE-RESULT-CONSTRAINTS would do is done on the prepass to save
* support test constraint propagation for blocks with with multiple

Make LDB quit on a ^D from a TTY instead of just ignoring the EOF.

* More consistent with the normal REPL
* The old behaviour would occasionally cause an infinite loop
of printing the LDB prompt, trying to read input, finding that
the tty was closed, printing the prompt again, etc.

Make MAP-ALLOCATED-OBJECTS use gencgc pagetable information to
skip over free dynamic space regions.

* More accurate ROOM results (previously all empty space up to
the fake allocation pointer would get counted as conses)
* Usually faster
* Needed for some GC work that might get committed in the future
* Genesify the GENCGC page size, while since it's now needed

Oops. Off-by-one in meant that the shorter MOV instruction
wasn't getting used quite as often as possible. Use a check for
(signed-byte 32) instead of (signed-byte 31) to pick between the
C7 and B8 opcodes. Shrinks the x86-64 core by 70k.

Document what we've learnt about discriminating functions
in the internals manual
... now we depend on dot (graphviz) to draw pretty state
transition graphs.
... lots o' text. I hope it's clear.

(it would be good to upload this to the web somewhere, in
order to be the top hit for e.g. "PCL CONSTANT-VALUE" on search
engines, so that the next person to hit the swamp has a chance
to get out before it's too late. Hack the Makefile enough so
that we can build an html version of an internals manual.)

More PCL smallification.
... the ACCESSOR-SLOT-VALUE optimization creates a generic
function (using load-time-value) when it sees
a form like (slot-value x 'constant). That's fine,
... these generic functions are also created at class
initialization time, three per slot. This hurts
now that we're creating classes eagerly (so that the
mop functionality works) as even condition classes
and structure classes cause these gfs to come into
... so, rearrange things so that only those generic functions
which are needed are created. Never create one with
a slot-missing method, as the automatically-generated
method will fall through to the full call and get there
eventually, anyway.
... this causes slot-missing from slot-value outside of methods
to be slower if (and only if) no slot of that name
exists in the image anywhere. We could potentially
improve fall-through-to-slot-missing performance.
