[JSC] Lower GlobalIsNaN to NumberIsNaN when input is DoubleRepUse
https://bugs.webkit.org/show_bug.cgi?id=290798
rdar://148279067
Reviewed by Yijia Huang.
NumberIsNaN(DoubleRepUse) and GlobalIsNaN(DoubleRepUse) are the exact
same. We should just lower GlobalIsNaN to NumberIsNaN when using
DoubleRepUse.
