c4d3a110a2 Adjust position recorded for call expressions. 
For calls of the form ident(...) record position of the identifier as the position of the call. For other calls record positions of the opening parenthesis.

This guarantees that for expressions of the form function(){}() call position will not intersect with positions recorded for function literal which is used by the debugger for scope chain resolution.

04f0e33229 Fix handling of foreign callbacks in DefineOwnProperty. 
We use foreign callbacks to make some properties shadow internal values
but still behave as data properties from within JavaScript. This means
when a value is passed to Object.defineProperty() on such a property,
it should update the internal value instead of redefinind the property
and destroying the shadowing.

a457040ca6 Ensure that non-optimized code objects are not flushed for inlined functions. 
Collector was flushing them if optimized code was reachable only through the stack (not through the JSFunction object) which happens when you have a pending lazy deoptimization.

Also prevent v8::Script::New from leaking internal objects allocated by the compiler into outer HandleScope.

ebccde15bc Don't preparse large files to find boundaries of lazy functions. 
Instead use the preparser inline to parse only the lazy function
bodies.

This is still disabled for small files.
More measurements are needed to determine if lazy-compiling small
sources is worth it.
