2eef2ce409 optimizer: fix inference bug 
The optimizer's inference that could incorrectly that that a
conditional produced a flonum (when it actually produced a fixnum or a
fixnum in one branch and flonum in the other).

d1be74fc3b compiler letrec_check pass: recognize effect-free primitives 
As in "Fixing Letrec". This improvement corrects a performance
regression with the revised expansion of R5RS `letrec`, which
wraps right-hand sides with `values`.

Besides detecting effect-free primitives, we have to fix the
treatment of the right-hand side for a multi-binding `letrec-values`
clause. For now, we conflate all of the bindings in a single
clause.

9b1a2e7b37 JIT: minor comparison repairs 
Fix some comparisions that are written as pointer comparisons
when they're actually integer comparisons. Also, remove an
unnecessarily slow variant of pointer compairson for x86_64.

c0ec9702e8 JIT: fix potential problem in transition to 64-bit jumps 
On x86_64, the JIT compiler initially generates code with 32-bit
jumps, but it switches to 64-bit jumps when so much code is allocated
that it gets spaced out enough. That transition could happen during a
recursive call to the JIT compiler or while one place is in the JIT
and other installs a shared code pointer, in which case a bad jump
could be generated. This problem is unlikely to happen, but it looks
possible.

9393592a80 optimizer: another little step toward type inference 
Generalize some of the tracking and optimization of predicates
with respect to constructors and bindings.

This generalization exposed an old bug in the optimizer, which is
that information accumulated in the "then" branch of a conditional
was not reliably flushed when continuing analysis after the conditional.

eac2ce0ef6 optimizer: ad hoc optimization of predicates applied to constructions 
This is probably more of a job for Typed Racket, but maybe it's
useful to detect some obviously unnecessary allocations of lists, etc.

2b33b8d966 scriblib/figure: make figure hyperlinks show start of figure 
... instead of putting the figure's caption at the top of the
browser window.

I can't decide whether I like the technique here, which is to use
JavaScript to move a figure caption's <a name=...> when the page is
loaded.  On the one hand, fixing up HTML via load-time JavaScript code
seems ugly compared to generating the right HTML in the first place.
On the other hand, it simplifies the generatation of a
backend-independent Scribble document (i.e., don't try to generate
different target locations for HTML and Latex), and HTML-specific
behavior seems properly handled at the HTML/JavaScript level.

They don't work if the code is compiled and do if it isn't, which causes
interesting test case failures.
