[JSC] Converting Double -> Bool should be branchless
https://bugs.webkit.org/show_bug.cgi?id=319790
rdar://182662714
Reviewed by Keith Miller.
Converting Double -> Boolean can be done with branchless JIT code
(compareDouble). This patch applies it. FTL is already doing so, so we
do not need to have additional change in FTL.
