The patch is applied to ChangeLog with the "--index" option, which already updates the index of the file. For resetting the ChangeLog to the trunk revision, the trunk branch needs to be stated explicitly in the checkout, otherwise it checks out the already patched HEAD.

After this change, you can just call DumpBacktrace in any function. Previously
the only function printing stack traces was V8_Fatal, but that also terminated
the program, so not very useful for debugging.

Note that DumpBacktrace is roughly equivalent to base::debug::StackTrace
functionality in Chromium, except less fancy, but it's enough for us.

OutputStream and ActivityControl are used only by heap profiler so I moved their definition in v8-profiler.h to not clutter v8.h

This uses the following approach to modify the trunk change log:
- Calculate the new change log entries
- Apply changes to the bleeding edge change log (this will be removed in a follow up CL)
- Apply the diff between BE and trunk to trunk (this includes the diff of the change log)
- Reset the change log to the version on trunk
- Reapply the new change log entries

This patch includes 3 fixes for veneers emission.

1) Block veneer pools emission in the PatchingAssembler.
2) Fix the check for veneer pool emission just before a constant pool.
3) Forbid copy of labels. The list of JumpTableEntry used to track the
   deoptimization table entries would make copies of the labels when growing.
   Doing so, it would confuse the Assembler that was tracking the labels via
   pointers.
