Running the libfuzzer fuzzers locally (with an experimental flag turned
on) found crashes, but did not produce crash files because we were
generating a software interrupt ("trap") instead of properly aborting.
Disabling the "hard-abort" feature fixes that.

This will hopefully not flush out previously missed crashes. If so,
please do manually bisect across this CL, instead of assigning to me :)

Drive-by: Move more initialization logic from {InitializeFuzzerSupport}
to the {FuzzerSupport} constructor, where other similar work is
performed.

A couple of customers have asked about using devtools to get information
about temporary allocations, with the goal of reducing GC time and/or
peak memory usage. Currently, the sampling heap profiler reports only
objects which are still alive at the end of the profiling session. In
this change, I propose adding configuration options when starting the
sampling heap profiler so that it can optionally include information
about objects which were discarded by the GC before the end of the
profiling session. A user could run the sampling heap profiler in
several different modes depending on their goals:

1. To find memory leaks or determine which functions contribute most to
   steady-state memory consumption, the current default mode is best.
2. To find functions which cause large temporary memory spikes or large
   GC pauses, the user can request data about both live objects and
   those collected by major GC.
3. To tune for minimal GC activity in latency-sensitive applications
   like real-time audio processing, the user can request data about
   every allocation, including objects collected by major or minor GC.
4. I'm not sure why anybody would want data about objects collected by
   minor GC and not objects collected by major GC, but it's also a valid
   flags combination.

Check whether the exception phi for the accumulator (i.e. the exception

maglev node liveness can differ from bytecode liveness, since the
bytecode accumulator could have been considered "live" just because of a
move to a (dead) register.

Use Script as the key for the template object cache, instead of the
SharedFunctionInfo. This is because SharedFunctionInfos can be garbage
collected and then later recompiled, which would mean that we break the
spec's expectation that the template object stays constant.

Now the association of cached template object with SharedFunctionInfo is
via the function_literal_id of the SharedFunctionInfo, stored on the
CachedTemplateObject. These are linearly searched, similar to the linear
search over slot ids.

This struct represents the freelist of an ExternalPointerTable and
contains both the size and the head of the freelist. It is encoded and
stored as a single Atomic64 field (freelist_) inside the
ExternalPointerTable class. This ensures that the freelist head and size
are always synchronized.

Previously, the freelist size was encoded in freelist entries in the top
bits. This only works as long as the maximum table size is relatively
small however, as it requires both the freelist size and the index of
the next entry on the list to fit into 24 bits. To allow for bigger
maximum table sizes in the future, this CL moves the freelist size
directly into the table as part of the freelist_ field.

During a stack switch, the stack state is temporarily inconsistent when
the old stack is marked as "inactive" and the new stack is not yet
marked as "active".

Ensure that the WasmAllocateSuspender runtime function is not called in
an inconsistent state. It can trigger a GC, and we need a consistent
state to iterate the roots.

Wait until the end of the function to mark the current stack as
"inactive", so that it is still marked as "active" when it is
potentially visited.

Before, import and export wrappers were cached based on their
signature. This change
- makes wrapper canonicalization consistent with that of types and
  call_indirect signatures under --wasm-type-canonicalization,
- removes the last uses of signature maps, which will enable us to
  remove them in a future CL.

Ignition remembers the correct context to restore when entering an
exception handler by moving the context to an interpreter register
when entering a try block, and restoring it from there when unwinding
the frame and entering the catch block.

Maglev code has to do the same by taking the context from the
appropriate register for the handler's frame state.

This error type is very common and deserves its own error message
instead of the generic "Unexpected value" one.

Move the CompilationInfo out of the GraphProcessor and into the
individual NodeProcessors, allowing them to hold it as a field rather
than getting it passed in via the various process methods. This will
allow us to write graph processors that don't have/need access to the
compilation info.

Joining a queue-using process can deadlock if the child process is
about to write to the queue, but the parent process wants to join the
child. To fix this, we now drain elements from a separate thread of
the main process.
