There are only very few custom compiled IC handlers left that go in there, and for each compiled handler we only have 1 cache hit on top25; maximally saving 60ms over 33s. Additionally we'll migrate the remaining handlers to data-driven handlers anyway. Let's try to remove this code.

ZoneList still used List as a base class, so this CL merges the two
classes together. We also remove unused functions in List and ZoneList.
We keep the inline header but move it to src/zone/zone-list-inl.h. The
includes that use this header are still quite tangled, but we can fix
that later.

In this CL I implement streaming compilation for WebAssembly,
as described in the design doc I have sent out already.
In this implementation the decoding of sections other than the
code section is done immediately on the foreground thread.
Eventually all decoding should happen in the background. I
think it is acceptable to do the decoding on the foreground
thread for now because I have finished it already, and
decoding in the background would add even more complexity to
this CL.

The interpreter was not able to call imported wasm functions (hitting
UNIMPLEMENTED). This CL fixes this by creating a "CWasmEntry", which is
signature-specific. It has JS linkage and receives the wasm code object
to call and a buffer containing all arguments (similar to the
interpreter entry). It loads all arguments from the buffer and calls the
given code object.
The c-wasm-entry code objects are cached per instance, such that we
only create them once per signature.
These wasm entry stubs will also allow us to call back to compiled code
from the interpreter, which we might want to do to reduce the slowdown
of executing wasm for debugging.

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.

We optimize parallel moves performed before a TailCall by grouping adjacent
pushes. This way, we may use a single instruction to push multiple registers at
once. However, we also have support for pushing immediates and stack slots for
which the benefit is questionnable therefore this patch removes support for
them.
Concerning immediate pushes, it looks like a mistake since we do not have
support for this case in `AssembleMove` so this patch removes it. Furthermore,
if we add a test for this case, we see that a `push ip` instruction is
generated, effectively pushing whatever was in `ip` at the time instead of
pushing a constant.
Concerning stack slot pushes, we generate a more or less equivalent sequence of
instructions.
Finally, grouping floating point pushes is not used anywhere so this patch

Most prototype implementations are not fully supported in the
interpreter. This is the case at least for exception handling, simd, and
atomics. Any function can be redirected to the interpreter though,
either by passing --wasm-interpret-all, or by dynamically redirecting to
the interpreter for debugging.
Making the flags experimental keeps the fuzzer from playing around with
these flags.
Drive-by: Refactor tests which explicitly set the prototype flag to use
a new scope for that.

All targets (at least on sanitizer builds) unconditionally depend
on //build/config/sanitizers:deps.
It is necessary for bug 593874 that all targets now also depend
on //buildtools/third_party/libc++:libcxx_proxy. This requires
adding a new "global dependency": //build/config:exe_and_shlib_deps.
This CL updates references to sanitizers:deps to instead refer to
//build/config:exe_and_shlib_deps.

This header file is only used from tests.
Also, move the LoadStoreOpcodeOf method (only used in tests) from
wasm-opcodes.h to wasm-macro-gen.h.

Reason for revert:
I think that this CL breaks chromium compilation on windows with clang (). All other CLs in the list looks trivial and don't change test/unittest/BUILD.gn.

As the code isn't used, but would have to be ported from hand-written
assembly to CodeStubAssembler anyways, I propose to remove it and
restore it if we decide that we actually need it.
