The new ParserCheckpoint mechanism resets some state, notably the
bailout ID counter but also some statement counters (only applicable
once we get "do" expressions) when we decide to reinterpret a comma
expression as arrow function arguments.

In doing so also remove all references to the --harmony-collections flag.
Due to the way context snapshotting works, it's not possible to simply
enable the flag by default.

The FunctionState corresponding to the arrow function's body should be
torn down before the function literal is allocated, so that the function
literal gets a bailout id for the environment in which it appears.

We will also need to rewind bailout IDs in the environment of the
function literal, to return IDs allocated for arrow function arguments.
This will come in the next patch.

Allow to pass the set of supported CPU features to
the InstructionSelector, so it can be tested without
messing with the command line flags.

Also add InstructionSelector sample for ia32.

* Consistently enable C++11 features on all platforms.
* Use the same ARM toolchain version as Chrome.
* Make clang the default on Mac OS X, just like Chrome.
* Use C99 on Mac OS X, again following Chrome.
* Small build fixes.

Move to globals.h so we do no longer skip any number of
tests. Introduce V8_TURBOFAN_BACKEND, which is 1 if we
actually have a backend and want to compile it, but don't
run the tests.
