e9aa21849b Reimplement Splay Tree in JavaScript (and add unit tests!). 
This is the first step in reimplementing tick processing scripts in
JavaScript. The goal is to have the same source both for Dev Tools and
Golem, so Python implementation will be removed to avoid code
duplication.

The implementation follows the Dev Tools style: namespaces and JSDocs
are used.

3c2a7bdf21 Add name inference for anonymous functions to facilitate debugging and profiling of JS code. 
Currently function name inference is wired with AST optimization pass to avoid introducing another pass over AST. A better solution would be to rewrite AST visitors so they can be naturally combined together in a single pass, as their current implementation doesn't allow it.

For examples of cases where function names can be inferred, see the tests file.

0eb4dea12d Implemented "no heap access" mode for JSFrame which is used for stack sampling in profiler. 
As I discovered that JSFrame accesses SharedFunctionInfo only to calculate caller SP and the latter is not used in profiler's stack sampling, I disabled accessing heap objects in JSFrame when doing stack sampling. This finally made V8's profiling stable when used from Chrome on a real web app.

a74fcf458c Fixed the step in handling for function.apply. 
The generic step-in mechanism floods the function called with break points to ensure a break is hit when entering the function. This generic mechanism was also used for function.apply. The code for function.apply contains a keyed load IC which was patched when stepping into function.apply. However function.apply enteres an internal frame not a JavaScript frame. This caused the logic for returning from the break in function.apply to fail as it forced a jump to the IC on the top JavaScript frame. The top JavaScript frame was the frame for the function calling function.apply not the frame for the apply function. Now returning from the break point in the keyed load IC in the apply code caused a jump to the code for the call IC for the function calling function.apply in the first place. Not a pretty sight.

Step-in now handles function.apply as a separate case where the actual JavaScript function called through apply is flodded with breakpoints instead of the function.apply function.

35d6c8fb03 Remove ENTER_V8 from small API functions that do not need access to 
V8's heap or only need read access.

This means that IsDeadCeck and EnsureInitialized could sometimes be
called without having already entered the VM.  To simplify things,
this is made always the case.  A couple of error callbacks do not need
to leave V8 because they haven't entered.

Consistently enter V8 after LOG_API (since LOG_API is sometimes before
EnsureInitialized or IsDeadCheck).

This all should have no effect unless V8 is built with
ENABLE_HEAP_PROTECTION and run with --protect-heap.
