f1149734fc Partial fix for V8 issue 1079. 
Record a safepoint with a deoptimization id for throw in optimized code.  We
don't seem to much care what the AST ID is because we will not be using it
for lazy deoptimization (throw doesn't return to the point of throw).  For
hygiene we use the actual ID of the throw expression.  Throw is no longer a
control-flow instruction, but it's followed by an unconditional abnormal
exit.  This is required to insert a simulate between the throw and the exit.

Make our optimized treatment of Function.prototype.apply act like a call and
have side effects.  This ensures that it will get a lazy deoptimization
environment.  Use that deoptimization ID in the safepoint for the call.

Deleting a property was also missing a deoptimization ID, though there was a
deoptimization environment assigned to the instruction.  Record the
environment and use the deoptimization ID at the safepoint.

09b3041a57 GDBJIT: emit .eh_frame section on x64. 
This enables proper stack unwinding on x64.

Currently this requires V8 to be compiled without snapshot and --gdbjit-full to be enabled.

73a4ecfae1 A MessageObject is a purely internal object to hold information about 
an error message that needs to be generated and reported. This change
hides all of the error information from JavaScript code so user
callbacks cannot get hold of it.

cb0a7bc748 This fixes the issue with the deoptimizer trashing the reloc info before patching the code. 
If we, immediately after the deoptimization, but before actually
running the patched code, get a compacting GC, the addresses from the
calls might no longer be valid.

I have validated that this works by patching the existing code to
always do a compacting gc after we finish deoptimizing. I will create
a real regression test for this, but this includes additional code for
allowing us to force a deopt/opt from javascript test code. I will
land this in a seperate change.

93f8e3d821 Temporary disable comparison of optimizability of code objects in some cases. 
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.

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

dc61921bbf Fix reintroduction of global variables that have been deleted. 
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'.
