When invoking EQUALS JS builtin, 1st argument is passed as a receiver and
if it's a global object, it gets overwritten with global proxy object and
thus one gets incorrect results.

With crankshaft, a code object can change its optimizability: it can start as
optimizable code object, but later we can find out it was a bad idea to
optimize it.  Alas, currently we don't have a proper event to communicate
this back to logger.  Hence we temporary allow a code object to be viewed
as optimizable judging from logs while being unoptimizable judging from
heap traversal.

Do not use overwritten Object.prototype.hasOwnProperty and
Array.prototype.pop. Do not use split and join in the error formatting
implementation. They are too big to control and their generality is
not needed.

1. The placement of checks for negative zero has to be computed after
all conversion instructions have been inserted. I separated the code
into its own phase.

2. GVN need to take instruction flags into account when comparing
instructions for redundancy.

This stub is used for increment/decrement operations and unary plus.
The resulting code is more compact and faster than calling a JS builtin.

If ConfigureGlobalObjects below will fail, we still decide that initialidation
went smoothly as we check emptiness of result_ handle to see if initialisation
failed or not.

Deletion of global properties puts 'the hole' in the global property
cell and updates the property details in the property dictionary with
the information that the property has been deleted. When setting
global properties that have been deleted in generated code we just
store the new value in the global property cell. This does not update
the property details in the property dictionary. Therefore, it looks
like the property is not there eventhough it was just reintroduced.

Perform 'the hole' checks in generated code for global property stores
and bail out of ICs and optimized code if storing to a property cell
that contains 'the hole'.
