af24067fa5 Refactor the way we collect the information for associating type-related infos
with AST IDs. Previously 3 different places had to match in how they handle a
given case, now we are down to 2, with an even simpler logic.

The downside is that due to this simpler logic the allocated dictionary could be
larger than before, but test have shown that this happens *very* rarely, because
its capacity is rounded to the next power of 2, anyway. Furthermore, the oracle
doesn't live long enough that we should really care.

The whole oracle is probably still a bit too tricky in its details, but this is
at least a step into the right direction.

4fa40ebc78 Include the loop header block when eliminating stack checks
In simple unconditional loops - like the following - the hydrogen stack check elimination did not detect the call as the loop header block itself was not considered.

function f(o) {
  while(true) {
    o.a();
  }
}

8c538d9012 Made parser not accept unicode escapes inside "native" when used as a keyword.
This is a regression relative to the original behavior, when "native" was a keyword,
since keywords cannot contain esacpes.

Added tests for escapes and for not allowing line-terminators betwen "native" and "function".

480ec43c4e Make "native" not a keyword.
We now only recognize "native function" when it occurs in extension scripts
(parsing with a non-NULL extension), and only if there is no line-terminator
between "native" and "function" (so that it would otherwise be a Syntax Error).
Preparsing never recognizes native functions, which is acceptable since we
never preparse extension scripts (because we don't allow lazy functions
anyway).

Before, they had no extra slots and an extension object with one named
property.  Now, they use the extension slot for the property name and have
an extra slot for the thrown object.  This increases the size of the context
itself, but removes overall allocation and eliminates a level of indirection.

a4cf7be941 First steps towards better code generation for LBranch:
* AST Expression nodes get a separate testing ID to record type info in
   ToBooleanStub later. This is necessary to avoid clashes with other uses of
   already existing IDs.

 * In order to avoid threading the condition expression through tons of places,
   TestContexts carry it now with them. Note that we will probably only need the
   testing ID of the expression, but having the whole thing at hand makes
   debugging easier. Probably we will change this later...

5a236ce6fd Add support for hydrogen control instructions with >2 successor blocks.
This change makes the number of successors of a control instruction
configurable with a template parameter and changes the existing instructions
to use it.

To iterate over all successors I added an iterator instead of always calling
First- and SecondSuccessor.

508b22c436 "Deiceolate" Thread classes.
Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.

This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.

As a side effect, we have also fixed the DebuggerAgent test.

Thanks to Vitaly for help in fixing isolates handling!
