4a387c5b6a add some missing checks on bytecode parsing 
The `tests/racket/stress/fuzz' test fails much less frequently,
though problems certainly remain.

958352eefc fix futures bug related to GC 
When a future is blocked on JIT generation, a lightweight closure
is captured, and then the future moves on, the runtime thread would
correctly shift the on-demand JIT argument to the captured copy
of the runstack. However, it would also add 2 to that pointer
to use as the argv array, and the captured runstack is not allocated
to allow interior pointers, so a GC during on-demand JIT could
crash. The solution is to keep an offset alongside the argv pointer
during JITting.

8dd4f1de21 fix futures bug 
When `(continuation-mark-set-first #f ...)' should produce #f and
the continuation is lightweight-captured, the result was NULL
instead of #f.

885bf6555f fix future resume in runtime thread with extra stack space 
Also, fix the possibility that a future can shift from RUNNING
to PENDING while the runtime thread is checking PENDING then
RUNNING.

be80e7d864 fix an over-eager reordering by the bytecode compiler 
The over-eager transformation could be space-unsafe, and it
could duplicate an unsafe operation whose result is used only
once in a function that eds up being inlined multiple times.

99032a75d0 inline map', for-each', andmap', and ormap' 
More generally, support a
 (define _id (begin 'compiler-hint:cross-module-inline _proc-expr))
hint, which is how the compiler determines that `map', etc., are
candidates for inlining.

fac07b964d Make get-libs retry downloads if they look stuck. 
This resolves a problem with the osx64 machine, where downloads seem to
just get stuck after a while, without timeout errors.  Re-enable that
build.

779b419c03 first cut at cross-module function inlining 
Inline only trivial functions, such as `(empty? x)' -> `(null? x)',
to avoid generating too much code.

Bytecode includes a new `inline-variant' form, which records a
version of a function that is suitable for cross-module inlining.
Mostly, the variant let the run-time system to retain a copy
of the bytecode while JITting (and dropping the bytecode of)
the main variant, but it may be different from the main variant
in other ways that make it better for inlining (such a less loop
unrolling).

e438793d43 implement JITted x86 floating-point operations with SSE 
Currently, the choice of SSE vs. x87 is when Racket is compiled.
SSE is always used for x86_64 and on Mac OS X, and x87 is used
for other platforms.
