-----------
[WebCore] Adopt uncheckedDowncast instead of jsCast
https://bugs.webkit.org/show_bug.cgi?id=312668
Reviewed by Anne van Kesteren.
Replace all uses of jsCast in WebCore with uncheckedDowncast. This
unifies the casting system so that all type casts in WebCore go through
WTF's standard casting infrastructure.
Also update CodeGeneratorJS.pm so that generated bindings emit
uncheckedDowncast instead of jsCast, and add a check-webkit-style
rule to flag future uses of jsCast.
Where the original jsCast was a same-type cast (no-op), the cast is
simply removed. Where the original code used the *jsCast<T*>(&ref)
pattern, it is simplified to uncheckedDowncast<T>(ref) using the
reference overload.
