The _GLIBCXX_DEBUG macro is now set by default for Linux Debug builds
and can be disabled using the disable_glibcxx_debug=1 setting
(compatible with Chrome). This will help us catch problems earlier.

This avoids accidental coercion-to-bool when calling ReportMessage()
in the parser (e.g., from pointer types), and as a bonus makes callsites
easier to read.

Because we generated a different hash code for 0 and -0 we ended up
not even getting to the SameValueZero check.

After further spec reading it turns out that we should not do ToObject

Mechanical change.
This will break dependency between profiler-generator and heap-profiler-generator.
Later this will help us to reuse SourcePosition in cpu-profiler.

We accessed to cpu_profiler for tracking SharedFunctionInfo objects movements and used their addresses for generating function_id. Actually we could replace the manually generated shared_id by the pair script_id + position. In this case we can drop SharedFunctionInfo events support from cpu_profiler and remove the dependency.
BTW GetCallUid was used as an unique identifier of the function on the front-end side. Actually it is a hash which might not be unique. So I renamed GetCallUid with GetHash and implemented GetFunctionId method.

This saves space since OptimizeAsPrototype detaches from the transition tree, reclaiming intermediate maps. On gmail this corresponds to roughly 20% of all maps.

Rebase to latest and use branch created by git new-branch to get a patch that
only has the required changes. Created new branch, reset to HEAD and then
cherry picked across the changes

Add a link with instructions about how to assign v8
issues to the chromium roll commit message.
Remove googler mapping feature as it doesn't apply anymore
to any generalist sheriff.

Add() becomes AddLocalExport, which takes an export_name and a local_name.
New parsing tests exercise this.
Also start generating exports for default exports (though this doesn't yet
handle anonymous default exports).

then we should do a [[DefineOwnProperty]] on the instance.

function inherit(parent, child) {
function p() {}
p.prototype = parent.prototype;
child.prototype = new p();
}
Otherwise child.prototype[constructor] keeps alive p, p's context, the
initial map attached to p, and the (now empty) transition array of the
initial map.

The root of problem is the fact that we don't track the position of 'this' statement but use them when visit compare statement.
As a result we have -1 as the position of left expression and the resulting relative position is negative and doesn't fit into BitField.
