It would force us to make mjsunit.js strong-compatible, and that's too much for
now (for the upcoming features) and would have a ripple effect on other
tests. Especially debug-script.js which unships harmony features would break.

Fix compilation problem with android toolchain.
Added new INTERNAL_REFERENCE_ENCODED RelocInfo type to differentiate MIPS existing use of internal references in instructions from the new raw pointer reference needed for dd(Label*).

This adds a new ControlFlowOptimizer that - for now - recognizes chains
of Branches generated by the SwitchBuilder for a subset of javascript
switches into Switch nodes. Those Switch nodes are then lowered to
either table or lookup switches.
Also rename Case to IfValue (and introduce IfDefault) for consistency.

A function could be deoptimized due to a deopt in the inlined code.
The inlined function might be defined in another script. So we need to
track the information about the inlined functions (scriptId and offset).
We already have the tracking code which is behind FLAG_hydrogen_track_position.
So as the first step we need to make the info accessible by CPU profiler.
In the follow-up patches I'll add the code which will enable position
tracking and push the info into CodeEntry entries.

1) Mutually recursive functions
2) Strong code using non-strong var before declaration.
These test cases ensure that we don't accidentally kill these wanted behaviors
when adding restrictions to strong mode.

Use git hashes as keys when referring to releases, not
pure commit position numbers as those are not unique.
Better bailout to only check for recent releases.
Add new branching method with a roll branch in heads to
the v8rel test case.
Fix the way v8 is referred to in DEPS files in the test
cases. The test still had svn-number style.

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). :-/
