Opitmizes the JSC::ExecState::removeHostCallFrameFlag and
JSC::ExecState::hasHostCallFrameFlag calls away (file
qtscript/src/3rdparty/javascriptcore/JavaScriptCore/interpreter/CallFrame.h)
Thats the reason why an 0x1 pointer instead of an nullptr gets propagated
around.

so if you change these to static member funtctions instead of non-static to
remove/check for HostCallFrame it should work.
