Cached template objects only need to be cached for reference identity comparisons. If there is no strong reference to the cached template object, then there's nothing to compare it against if it were to be loaded from the cache, so we can hold it in the cache weakly.

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 message object) is dead, and don't assign rax to it if yes. Note that 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.

The numfuzz fuzzer.py has a loop to send a new test after receiving a result. When all test processors go into stopped state, attempts of sending new tests return False. That case wasn't handled here and we kept looping forever.
