>+        [JSC] Reduce size of SourceProvider
>+        https://bugs.webkit.org/show_bug.cgi?id=193544
>+
>+        Reviewed by NOBODY (OOPS!).
>+
>+        This patch attempts to reduce the dirty memory footprint by the following 2 optimizations.
>+
>+        1. Reordering the members of SourceProvider to reduce the size. This affects on JSC, and CachedScriptSourceProvider used in WebCore.
>+
>+        2. Create one SourceProvider for all the builtin code and use substring to create builtin JS functions.
>+           This reduces # of SourceProvider created for builtins.
>+
>+        3. Drop m_validated flag in SourceProvider since nobody uses it. It also deletes dead code in Parser.cpp.
>+
>+        We also remove the dead code using m_syntaxAlreadyValidated in Parser.cpp.
>+
>+        Unfortunately, MSVC does not accept super long C string literal. So instead, we construct combined string in a form of C array.
