The general, non-hacker meaning of "jit is enabled" would seem to
be pretty much what this function is already doing; and for that
matter, the same can be said for "JIT compilation is available".
We need something that's less tautological-looking.  Maybe along
the lines of

"returns true if a JIT compiler extension is available and the
<varname>jit</varname> parameter is set to <literal>on</literal>;
when this is true, JIT compilation will be performed."

?
