3348b5c2b4 Allow lazy compilation (and thus optimisation) of functions inside eval. 
For strict-mode eval, this requires _disabling_ lazy parsing of inner functions,
because we need to collect their free variables to do allocation for the
eval scope properly.

This patch adds the following three metrics for the --trace_gc_nvp option.

nodes_died_in_new_space_; // Number of died nodes in the new space.
nodes_copied_in_new_space_; // Number of copied nodes to the new space.
nodes_promoted; // Number of promoted nodes to the old space.

6b16d0bcae Make Object.observe on the global object functional 
The approach in this change is to handle the unwrapping/wrapping of the global object transparently with respect to the JS implementation of Object.observe. An alternate approach would be to add a runtime method like %IsJSGlobalProxy and %UnwrapJSGlobalProxy, but it seems ugly to give JS (even implementation JS) access to the unwrapped global.

cec0745aa2 Introduce callback for resolving global object name while taking heap snapshot 
Heap profiler currently gets "document" of global objects while taking snapshot (to later retrieve its "URL"). This is unsafe as there may be no current v8 context when the property is requested while corresponding property accessor may make some assumptions about the context stack during its invokation. Several crashes were reported due to this problem:
https://bugs.webkit.org/show_bug.cgi?id=103076
https://crbug.com/162121
https://crbug.com/132727

This patch adds a callback for resolving global object names and avoid the crashes.
