Adds support for off-thread allocation to Script allocation and line-end calculation. This includes adding support for keeping/merging a script list on the OffThreadIsolate, and adding syntactical support for logging (in the future this could do actual logging).

This makes creating whitelisted runtime functions more permissive on fuzzers (when --allow-natives-for-fuzzing is passed). - Runtime functions with too few arguments are replaced with undefined. - Superfluous arguments are ignored. This reduces syntax-error rate on fuzzers. Also prevents dcheck errors when fuzzing debug builds and fuzzers use too many arguments for runtime functions.

When delaying finalization we considered the maximum of the current time to task and the recorded average. In case there's no recorded average the GC would consider the current time to task as estimate which is too aggresive as V8 may never get a task executed. Be fully conservative about recorded task times and bail out in such cases.

Update external memory counters when using ArrayBufferExtensions. In case the array buffers are swept concurrently, the counters are updated at the beginning of the next minor/full GC. A subsequent GC is going to update counters faster. ArrayBufferExtension now stores the accounting_length such that the sweeper always knows how much memory to deduct from the external memory on destruction. ArrayBufferList now also tracks the size of all ArrayBuffers in it.

Joakim Bengtsson authored
The logic for V8 GC normally only takes the external memory growth since last mark-compact into account. Unfortunately, the amount of external memory recorded at the end of MC is often too high. The reason is that it might take a while for the external memory associated with the GCed objects to be released (e.g. V8 itself post a task to release external memory for ArrayBuffer backing stores). In a worst case scenario GC is driven only by external memory and none of the external memory is released by the end of the MC. Then each MC will record the external memory at its highest point and the GC logic will allow the external memory to grow a bit higher each time which can lead to excessive memory use. This patch improves the situation a bit by calculating the growth from the lowest external memory seen since the last MC. That way the growth calculation will be offset from a level presumably closer to the intended one (to what it would have been if the external memory associated with the GCed objects was released during the MC). Now, this fix is not perfect because it can be thrown off by external memory growth occurring before the lingering memory is released. However, it seems to work rather well in practice (e.g. when playing MSE video on YT).

This time, move the dcheck below the stack pointer check. It turns out we call into this with current state == JS, but only when js is on the stack, so we can just move the check lower.

This change moves the definition of the bits stored in DebugInfo::flags to Torque, and updates the only Torque usage of that field to use more natural syntax. This is intended as an example of common patterns found in various other classes. Several supporting changes are required: 1. Add a new type representing a bitfield struct stored within a Smi. It is currently called SmiTagged, but I'm open to suggestions. 2. Add an enum-style output for Torque bitfield structs whose bitfields occupy only one bit each. 3. Add a new case to MachineOperatorReducer that makes the generated code for IncBlockCounter match with what was generated before this change. 4. Add support for reporting these bitfields in the postmortem debugging API. The format matches existing bitfields but with an offset value that includes the SMI shift size.
