One consequence is that the properties on the builtin object are no longer

Unfortunately, we cannot actually switch the library scripts to strict mode
by default, because that makes observable things like poisoned .caller properties
for library functions.

Remove the static qualifier from functions in header files.
...
This shaves 416+ KB, just under 1% off the size of the debug d8 executable
on Linux (mostly because the CheckHelper functions for assertions were
getting separate copies for each compilation unit). The difference in
release builds is negligible---a size reduction of 0.1%.
Also, change namespace-level 'static const' variables to remove the static
storage class as it's the default.

Add v8::HeapGraphNode::GetHeapValue method.
...
This allows getting a heap object by a heap snapshot node for further
inspection. Very useful for objects from bindings that mostly have
getter-provided fields.

Reorganize object type enum, such that proxies are no longer in the middle
...
of the range of proper JS objects.
Unfortunately, callable types no longer form a range now. However, there
are only two anyway. We put them at either end of the range of JS object
types so that certain compares can be combined.
