To make the existing mechanism for printing JSON for turbolizer able to
print types other than the ones stored in the nodes (so the verifier can
print its own types here), this CL restructures the printing mechanism
into a single non-private class that can be inherited to override
certain parts of the printing. In this CL only GetType is made virtual
to allow verifier to override it, but additional parts can be made
overridable whenever necessary.

Bring back raw SetAccumulator, instead of the separate
SetAccumulatorToNew/ExistingNode. SetAccumulator (and StoreRegister) are
now expected to only ever be called on new Nodes, with some DCHECKs
tracking which nodes are new guaranteeing this.

API logging has not been used in a while and we have valid alternatives:
- Runtime call stats
- Profiling
- Timer events

Together they make --log-api superfluous and we can remove it and reduce
the number of branches when calling into the V8 API.

Instead of using cipd for dsymutil (which is updated via the autoroller),
chromium/src downloads the dependency directly from a storage bucket
(https://crrev.com/c/3564507).

This rolls the approach into v8's DEPS. Additionally, it manually rolls

The tier up check in br_if is only executed conditionally, so it is
not allowed to update any cache state. Later code would work with that
updated state, even though the corresponding code would not have
executed.
There was a partial implementation for this by passing in a scratch
register for {TierupCheck}, but {TierupCheckOnExit} has the same
problem, and needs up to three scratch registers.

Until we come up with a better solution, just snapshot the cache state
before doing the tier up check, and restore it later. This has some
performance cost, but it's an effective fix.

Opportunistically specializing the inlined function's signature
based on statically available type information in the caller is
currently important for performance, but can make inlining fail
if parts of the inlinee relied on the more generic types.
This patch addresses that problem by retrying with the original
signature in such cases.
Long-term, check elimination should be based on typed IR nodes
instead.

Port 9ca0bfef

Original Commit Message:

    This adds feedback collection to count the number of executions of
    call_direct instructions in Liftoff code. The purpose is better
    inlining decisions in Turbofan, which are enabled by having call
    count information for all kinds of calls.
    The new feature is gated on --wasm-speculative-inlining. While
    direct calls don't need to speculate about their target, the whole
    feedback collection infrastructure depends on that flag.

Replace by a unary right fold using the comma operator. This also
evaluates from left to right, so has the same semantics but uses
standard C++17 syntax.

It might be wrong for bytecode blocks that only juggle registers.

Sweeper needs to clean up slots in the OLD_TO_SHARED remembered set
as well in the future. Unlike OLD_TO_NEW or OLD_TO_OLD this remembered
set will not be reset after a full GC. So we will have to remove from it
both during and after a full GC when sweeping.

However in the current implementation we still reset this remembered set
in a shared GC. This only works because we scan all client heaps
during a shared GC anyways to rebuild the remembered set. We will get
rid of that when all required write barriers are implemented.

This will need re-work but it allows us to test for now.

For large BigInts, computing the decimal representation can take a
very long time, so send them as hexadecimal strings instead. Also
make sure to abbreviate the RemoteObject description for bigints
appropriately always.
