    Original commit message:
        Currently we do this dance between the CallConstructStub, the
        CALL_* builtins and the %GetConstructorDelegate, %GetProxyTrap,
        and %Apply runtime functions for every [[Construct]] operation on
        non-function callables. This is complexity is unnecessary, and can
        be simplified to work without any JS builtin. This will also make it
        a lot easier to implement ES6 compliant [[Construct]] for proxies.
    
        Also sanitize the invariant for CallConstructStub, which up until now
        always restored the context itself, but that force us to always create
        another copy of all arguments in case of proxies and other callables,
        so we can relax that constraint by making the caller restore the context
        (this only affects fullcodegen, since the optimizing compilers already
        properly restore the context anyway).
