[JSC] Add inherits<T>(VM&) leveraging JSCast fast path
​https://bugs.webkit.org/show_bug.cgi?id=183429

Reviewed by Mark Lam.

Source/JavaScriptCore:

Add new member function, JSCell::inherits<T>(VM&) and JSValue::inherits<T>(VM&).
They depends on jsDynamicCast<T> implementation and leverage JSType-based fast
paths defined in JSCast.h. We extract checking part as JSCastingHelpers::inherit
and construct jsDynamicCast and JSCell::inherits based on this.

And we remove several unnecessary casting functions (asRegExpObject, asDateInstance etc.).
In addition, we add jsDynamicCast fast path for RegExpObject by using existing RegExpObjectType.

We also fix the implementation of jsDynamicCast for JSObject since it uses LastJSCObjectType.
The embedder can add their extended object types after that.
