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.

BUG=
TEST=Manually confirmed that the "--trace_gc --trace_gc_nvp" option prints the metrics

This fixes a corner case where a code flushing candidate was evicted
from the candidate list without being revisited by the incremental
marker. An explicit write-barrier makes sure it gets revisited.

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.

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.

This changes how FunctionTemplate interprets a Signature that specifies
compatible receivers and arguments. Only the hidden prototype chain will
be considered when searching for compatible receivers. This prevents
JavaScript from modifying the inheritance relationship set up by the
embedder.

This tries to propagate exceptions which are externally thrown into
external try-catch handlers before scheduling them. This also allows
embedders to nest external try-catch handlers.

This just relands r11834.

This unifies the iteration logic of objects groups iteration in global
