Message:

[JSC] Remove non-LargeAllocation restriction for JSCallee
​https://bugs.webkit.org/show_bug.cgi?id=203260

Reviewed by Saam Barati.

Source/JavaScriptCore:

We now pass JSGlobalObject* instead of ExecState*. And we are getting VM& from JSGlobalObject*.
Because now accessing ExecState::vm() becomes less frequent, we can remove the restriction that
callee is only allocated in non-LargeAllocation, which restriction made ExecState::vm fast.

This patch renames CallFrame::vm to CallFrame::deprecatedVM. And we avoid using it as much as possible.
And we also remove the restriction that callee needs to be in non-LargeAllocation.
