Deletes the now unused Full-codegen compiler. Also removes some macro
assembler instructions which are no longer used.
Note: there is still additional cleanup work to do after this lands
(e.g., remove support for FCG frames support and FCG
debugger support, etc.), but this will be done in followup CLs to keep
this patch managable.

To speed up compilation times, jumbo allows files to be compiled
together. This is a well known method ("unity builds") to both
compile faster and create a poor man's "full program optimization".
We are only interested in compile times.
Background:

Note that jumbo builds are not enabled by default. To try this out,
add use_jumbo_build=true to your GN args.

the race that happens when
1) the mutator is invalidating slots for double unboxing or string
conversions
2) and the concurrent marker is recording these slots.
This patch adds a data-structure for tracking the invalidated objects.
Thus we can allow the concurrent marker to record slots without

This CL moves the last remnants of register configuration into

in preparation for caching StoreIC-Transition handlers in there.
This CL should not change behavior or performance.
The TransitionArray class no longer serves a dual purpose; it is now
simply the data structure serving that role. Further, it now supports
storing transitioning handlers in its "target" slot, which in turn have
a WeakCell pointing to the transition target (but this functionality
is not being used yet).
The interface for accessing a map's transitions, previously implemented
as a set of static functions, is now handled by the TransitionsAccessor
class. It distinguishes the following internal states:
- kPrototypeInfo: map is a prototype map, will never cache any transitions.
- kUninitialized: map can cache transitions, but doesn't have any.
- kWeakCell: map caches a single transition, stored inline. Formerly known
as "IsSimpleTransition".
- kFullTransitionArray: map uses a TransitionArray to store transitions.
- kTuple3Handler, kFixedArrayHandler: to be used in the future for caching
transitioning handlers.

This CL moves us much closer to the point where we can remove debugger-script.js and usage of debugger context from inspector.
There are three main parts left:
- managing breakpoints,
- inspecting stack and scopes (this CL),
- LiveEdit.
In this CL I moved all stack/scope inspection to native. As side effect running debugger and inspector tests are 10-20% faster (it's significant since not all of tests requesting break).
