Updated the comment about the optimization for tiny x (the previous
commit moved it).  This includes a comment that the "kernel" sine no
longer works on arg -0, so callers must now handle this case.  The kernel
sine still works on all other tiny args; without the optimization it is
just a little slower on these args.  I intended it to keep working on
all tiny args, but that seems to be impossible without losing efficiency
or accuracy.  (sin(x) ~ x * (1 + S1*x**2 + ...) would preserve -0, but
the approximation must be written as x + S1*x**3 + ... for accuracy.)
