Optimize Object.seal and Object.preventExtensions
...
They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.
This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).

This adds flags in Scope to track wheter a Scope uses "this" and,
"arguments". The information is exposed via Scope::uses_this(),
and Scope::uses_arguments(), respectively. Flags for tracking
usage on any inner scope uses are available as well via
Scope::inner_uses_this(), and Scope::inner_uses_arguments().
Knowing whether scopes use "this" and "arguments" will be handy
to generate the code needed to capture their values when generating

Clean up IC tracing for CallICs.
...
CallICs have had some confused tracing, because the IC state is not
entirely captured by the installed code stub - it lives in the type
vector.
Change tracing to be able to use the vector state changes instead.
Introduced a DEFAULT state to be used by all vector-based ICs.

Cleanup V8_TURBOFAN_TARGET definition.
...
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.

Cache IC handlers on the prototype's map if possible
...
instead of on the receiver's map. Lazily overwrite cached handler if it is
identical to the handler that just missed.
