Coverage updates are sent as deltas, and this means that it is very important that the consumer gets /all/ updates; otherwise, the coverage information will be wrong. Previously, we introduces the ability into the back-end to send triggered updates, i.e. updates that are triggered by the back-end at interesting points in time. These updates are delivered via an event, and any consumer must process these events. This CL introduces a flag to startPreciseCoverage that controls whether the back-end is allowed to send such triggered updates on its own initiative. The default is `false` to maintain backwards compatibility with consumers that don't yet handle the events.

This fixes a bug in lazy deopts caused by calls to the callback function in Array.prototype.reduce and reduceRight. The deopt continuation expects the *next* iteration's index value but we actually passed the current iteration's value. The user-visible effect of this bug was that sometimes, an unexpected additional call to the callback function would occur. It was introduced by https://crrev.com/c/1934329.

Nico Hartmann authored
This CL significantly reduces the size of CSA files generated from torque by introducing only those Phis at block entry that are required and otherwise uses defined values directly. To do so it does: - Define a DefinitionLocation that represents where a value is defined. - For each block compute all the definitions that reach that block and introduce a phi iff the reaching definitions for a value are not the same for all predecessor blocks. - In CSAGenerator map all DefinitionLocations to variables, such that if the same value is used in multiple blocks, it is mapped to the same variable without the need to pass it along the jump. This reduces both the arguments passed to Goto, Branch, ... and the variables that need to be passed to Bind when the block's label is bound. This reduces the number of temporary variables significantly. Temporaries are declared outside of blocks now in order to be accessible from other blocks. Drive-by changes: - Sequences of SetSourcePosition calls are merged if no output is generated between them. - Dead blocks are no longer generated in release builds.

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.
