  [WTF] MediaTime: compute flags on multiplication with doubles
https://bugs.webkit.org/show_bug.cgi?id=246746

Reviewed by Yusuke Suzuki.

The current multiplication algorithm in WTF::MediaTime updates the time
value without updating the flags. This becomes a problem if the
multiplication promotes the number to infinity.

This patch fixes this problem and adds a test for it.
