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.

 * 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...

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.

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!

Updated the armu.gypi to set values for variables which does not have a default. These variables was recently added to v8.gyp.

Moved the what will be shared between building the v8 library and the cctests to a separate include file. For now this file is currently only used by cctest.gyp. the reason is that the cctests are not just using the API but also internal functions so the C++ defines and optons needs to be the same when compiling the cctests files as when compiling the v8 library files.
