The --type_info_threshold is no longer supported for a long time and
doesn't do anything useful nowadays, so no point in having that around.
Drive-by-fix: Remove the FeedbackVector::ComputeCounts() logic, since
it's dead code anyways by now.

{FrameArray} needs a way to keep {WasmCode} alive from a JS container.
This CL instruces {GlobalWasmCodeRef}, which is the equivalent to a
global handle: It increments the {WasmCode} reference counter on
construction and decrements it on destruction.
The {GlobalWasmCodeRef} is held in a {Managed} from JS.

Before this change we had essentially two optimization limits, one hard
limit in the TurboFan pipeline (128KiB), and a soft limit in the runtime
profiler (60KiB). The hard limit was only relevant to --always-opt and
other internal test infrastructure, and the soft limit was always
enforced on regular JavaScript, but didn't properly disable further
optimization for the function (so for example --trace-opt would
continuesly report attempts to optimize the function).
Now with this change we only have the hard limit, set to 60KiB, in the
TurboFan pipeline and use that consistently.

This extends the existing PipelineStatistics in the TurboFan pipeline
(also used for Wasm) to emit trace events for the various phases of the
(optimized) compilation. This works for "disabled-by-default-v8.compile"
and "disabled-by-default-v8.wasm" categories.
We also rename the existing phase names to match the naming convention
for the V8 trace events (starting with either "V8.TF" or "V8.Wasm") to
make it easy to spot and categorize them in the trace viewer.
This can be seen in action here

Add tracing support for the %StackGuard() and %Interrupt() runtime calls
and the individual actions performed in StackGuard::HandleInterrupts().
This includes:
- "V8.GCHandleGCRequest" (in "disabled-by-default-v8.gc") when the
GC_REQUEST bit is set.
- "V8.WasmGrowSharedMemory" (in "disabled-by-default-v8.wasm") when
the GROW_SHARED_MEMORY bit is set.
- "V8.TerminateExecution" (in "v8.execute") when the
TERMINATE_EXECUTION bit is set.
- "V8.GCDeoptMarkedAllocationSites" (in "disabled-by-default-v8.gc")
when the DEOPT_MARKED_ALLOCATION_SITES bit is set.
- "V8.InstallOptimizedFunctions" (in "disabled-by-default-v8.compile")
when the INSTALL_CODE bit is set.
- "V8.InvokeApiInterruptCallbacks" (in "v8.execute") when the
API_INTERRUPT bit is set.
Now we also emit a trace event "V8.MarkCandidatesForOptimization" (in
"disabled-by-default-v8.compile") in addition to the above from the
RuntimeProfiler when we mark candidates for optimization at the end
of each stack check.
An example of the "V8.InstallOptimizedFunctions" in action (in the
trace viewer) can be seen here:

which is thus removed as part of this change.

In the implementation of WebAssembly.compileStreaming and
WebAssembly.instantiateStreaming, we did not handle the case where the
input, which is a Promise, gets rejected. When this Promise got
rejected, the Promise returned by compileStreaming remained pending
forever.
With this CL, the rejection object of the input Promise gets forwarded
to the result Promise.
I also extended the --wasm-test-streaming flag to provide
WebAssembly.compileStreaming and WebAssembly.instantiateStreaming
in d8. The difference to the Chrome versions of these function is
that d8 does not know about Response objects. That's why in d8
compileStreaming and instantiateStreaming expect a Promise to an
ArrayBuffer or a TypedArray and not to a Response object.

We were hitting a DCHECK in WaitFor() when rel_time was negative. This
was caused when GetNext() recalculated the wait time for a delayed
task. In the first part of the loop we moved all delayed tasks which
have passed their deadline into the immediate task queue. At the
bottom of the loop we assume that all delayed tasks in the queue
have a deadline in the future, but this isn't always the case as we
use a new 'now' value for the calculation, and time could have elapsed.
Fix this by using one 'now' value for an iteration of the loop.

statically links against shlwapi.dll. Shlwapi is only needed for a
single use within the debug stacktrace code and is therefore not needed
in most cases. Statically loading shlwapi also brings in user32.dll and
gdi32.dll, so this is a decent perf hit which is generally unnecessary.
This changes delayloads shlwapi so that is only loaded when actually
