+ _javascript_Core should build with newer clang

+
+ Reviewed by Geoffrey Garen.
+
+ Other than the JSC::SourceProvider::asID() change (which simply
+ removes code that the optimizing compiler would have discarded
+ in Release builds), we move the |this| checks in OpaqueJSString
+ to NULL checks in to JSBase, JSScriptRef, JSStringRef{CF} and
+ JSValueRef.
+
+ * API/JSBase.cpp:
+ (JSEvaluateScript): Use String() in case |script| or |sourceURL|
+ are NULL.
+ * API/JSScriptRef.cpp:
+ (JSScriptCreateReferencingImmortalASCIIText): Use String() in
+ case |url| is NULL.
+ * API/JSStringRef.cpp:
+ (JSStringGetLength): Return early if NULL pointer is passed in.
+ (JSStringGetCharactersPtr): Ditto.
+ (JSStringGetUTF8CString): Ditto. Also check |buffer| parameter.
+ * API/JSStringRefCF.cpp:
+ (JSStringCopyCFString): Ditto.
+ * API/JSValueRef.cpp:
+ (JSValueMakeString): Use String() in case |string| is NULL.
+
+ * API/OpaqueJSString.cpp:
+ (OpaqueJSString::string): Remove code that checks |this|.
+ (OpaqueJSString::identifier): Ditto.
+ (OpaqueJSString::characters): Ditto.
+ * API/OpaqueJSString.h:
+ (OpaqueJSString::is8Bit): Remove code that checks |this|.
+ (OpaqueJSString::characters8): Ditto.
+ (OpaqueJSString::characters16): Ditto.
+ (OpaqueJSString::length): Ditto.
+
+ * parser/SourceProvider.h:
+ (JSC::SourceProvider::asID): Remove code that checks |this|.
