[plt-scheme] JIT and flonums

The latest in SVN (v3.99.0.7) includes new JIT support on x86 for
inlining flonum (i.e., inexact real) arithmetic. I expect to fill in
x86_64 and PPC support next week.

This change makes inexact-heavy microbenchmarks run 2-3 times as fast.
It might be useful for real programs, too, but I don't seem to have any
interesting floating-point applications to try out.
