    [stubs] Simplify the non-function case of CallConstructStub. · 622fa0ea
    bmeurer authored
    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).
