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.

b625ce2b6b Fix a bug in scope analysis. 
When recompiling code (e.g., when optimizing) we could incorrectly hoist
some function expressions.  This leads to incorrect results or a crash.  The
root cause was that functions were not correctly categorized as expression
or declaration at parse time.

This requires some extra hoops to prevent the print name "anonymous" for
functions created by 'new Function' from establishing a binding.

When creating a CompilationInfo we always have the script and can
determine if it is a natives script.

Now that all natives functions are recognized as such, many of them
are called with undefined as the receiver. We have to use different
filtering for builtins functions when printing stack traces.

Also, fixed one call of CALL_NON_FUNCTION to be correctly marked as a
method call (with fixed receiver). Now that CALL_NON_FUNCTION is
marked as a native function this caused the receiver to be undefined.

890bc1607a Fix a potential crash in const declaration. 
Declaration of const lookup slots would trigger an assertion if there was a
setter somewhere in the prototype chain, and that setter was shadowed by a
non-readonly data property also in the prototype chain.

fe23339bdd Fix a bug in for/in iteration of arguments objects. 
We did not properly combine the property names from the parameter map
and the arguments backing store.  They could overwrite each other and
be unsorted.

Also fix an unrelated bug: deleting from a dictionary-mode arguments
backing store could corrupt the parameter map.
