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.

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.

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
