Use one object instead of two for closures, eliminating ScopeChainNode
https://bugs.webkit.org/show_bug.cgi?id=95501
Reviewed by Filip Pizlo.
../JavaScriptCore:
This patch removes ScopeChainNode, and moves all the data and related
functions that used to be in ScopeChainNode into JSScope.
Most of this patch is mechanical changes to use a JSScope* where we used
to use a ScopeChainNode*. I've only specifically commented about items
that were non-mechanical.
* runtime/Completion.cpp:
(JSC::evaluate):
* runtime/Completion.h: Don't require an explicit scope chain argument
when evaluating code. Clients never wanted anything other than the
global scope, and other arbitrary scopes probably wouldn't work
correctly, anyway.
* runtime/JSScope.cpp:
* runtime/JSScope.h:
(JSC::JSScope::JSScope): JSScope now requires the data we used to pass to
ScopeChainNode, so it can link itself into the scope chain correctly.
* runtime/JSWithScope.h:
(JSC::JSWithScope::create):
(JSC::JSWithScope::JSWithScope): JSWithScope gets an extra constructor
for specifically supplying your own scope chain. The DOM needs this
interface for setting up the scope chain for certain event handlers.
Other clients always just push the JSWithScope to the head of the current
scope chain.
