Avoid fp->integer UB throughout WebKit repository
https://bugs.webkit.org/show_bug.cgi?id=310697
rdar://173311131
Reviewed by Chris Dumez and Dan Hecht.
Apply 309786@main change throughout the WebKit repository. When
converting fp to integers, if it is not fitting in a range of integer's
representable range, it is UB. And the recent clang is leverageing this
UB a bit too aggressively and causing breakage of semantics in the code
when it is used in an UB manner.
