We already use recursion to iterate over transition trees elsewhere, so this should be safe wrt. call stack height.

For flushing the input queue, use the input queue lock. Introduce an
explicit refcount to make sure we don't delete the thread object before
all jobs are finished.

We no longer expect NewError to return an empty handle to signal termination
exception, since TryCall simply requests a new terminate exception interrupt.

This implements a special case of block cloning to recognize constructs like
if (a ? b : c) { ... }
that happen to be generated by Emscripten quite often.

This is done using desugaring. Before this we had:
result = iterator.next()
with this we instead do:
!%_IsSpecObject(result = iterator.next()) &&
%ThrowIteratorResultNotAnObject(result)

The adder should be gotten before the iterator.
Motivation: Once this is done we should be able to use a for-of loop
instead which leads to cleaner code and correct behavior once the
for-of loop correctly supports abrupt completion.

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.

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.
