With the new ES6 semantics super construct calls are only valid in
a constructor in a derived class. This is something that is
statically known and we report early SyntaxError in case it occurs.
We therefore do not need to track this any more.

In an innocuous cleanup patch, https://code.google.com/p/v8/source/detail?r=21621,
some boolean logic got mixed up and the Hydrogen code for TypedArrayInitialize
was changed to always bail out. This swaps the logic appropriately.

1) create beefy RelocInfo table when cpu profiler is active, so if a function
was optimized when profiler was active RelocInfo would get separate DeoptInfo
for the each deopt case.

2) push DeoptInfo from CodeEntry to ProfileNode.
When deopt happens we put the info collected on #1 into CodeEntry and record stack sample.
On the sampling thread we grab the deopt data and append it to the corresponding ProfileNode deopts list.

Sample profile dump.

This is needed as normal chromium checkouts don't fetch
branch-heads.

These branches will also be replicated by GitHub and are
fetched when cloning from the repository.

The expected object size will be the same or smaller than
before as we currently push the same information onto the
candidates branch (which already is in refs/heads). The only
difference is the increasing number of refs in refs/heads.

Parser must be able to operate independent of Isolate and the V8 heap during
parsing. After the heap-independent phase, there is a heap dependent phase,
during which we internalize strings, handle errors, etc.

This makes Isolate (also via CompilationInfo) unaccessible during parsing, and
thus decreases the probability of accidental code changes which would add
heap-dependent operations into the heap-independent phase.

Since Isolate is also accessible via CompilationInfo, now CompilationInfo is
only passed to the entry points of parsing, and not stored in Parser.
