Previous approach for property reconfiguration was to create a free-floating map with generalized representations of all fields. This patch does it right.

When property is reconfigured either by changing its kind (kData <-> kAccessor) or its attributes it implies creation of a new branch in transition tree. If such a branch already existed before reconfiguration then it should be merged with the old (or source) branch of the transition tree. Merging procedure includes all the heavy machinery such as property location changes (kDescriptor -> kField), field representation/field type generalization, map deprecation, etc.

The heuristic is quite naive at the moment (build a frame iff the
register allocator needed spill slots), we can improve that later.

Use simple old-skool constructors instead. Note that the long repeated
member initializer lists could be reduced a bit by using C++11's
brace-or-equal initializers, which are actually recommended by the
Google C++ style guide in this case, but the ARM toolchain is still
buggy in this area (see patch sets 1 and 2).  :-/

Revert of Don't always bail out of GenerateTypedArrayInitialize (patchset #1 id:1 of https://codereview.chromium.org/922393003/)

Reason for revert:
Speculative revert. This CL seems to break octane.

Original issue's description:
> Don't always bail out of GenerateTypedArrayInitialize
>
> 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.

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.

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.
