This removes the field in question to make it simpler to serialize and deserialize modules without having to worry about the state of lazy compilation. It is always possible to clone a non-anonymous builtin, even without having this module-wide field.

During GC fuzzing we combine multiple tests and run them inside a wrapper that needs to ignore all errors/exceptions/asserts to keep the combined tests running.

When a tab in Chrome gets refreshed, the refreshed page reuses the isolate of the original page. This means that at the moment, AsyncCompileJobs which were stared on the original page do not get aborted and will therefore eventually finish and resolve their promise. With this CL I abort all running AsyncCompileJobs when V8 gets the tab refresh signal, i.e. Isolate::ContextDisposedNotification. Note that I cannot just call CompilationManager::TearDown because it assumes that there are no pending tasks anymore.

Leszek Swirski authored
Suspend points (inside generators and async functions) have slightly funky semantics when it comes to liveness, as they save and restore a chunk of the register file as-is. In particular, this means that granular liveness information is lost, as it is assumed that all registers in that chunk of the register file are live in a suspend. Rather than marking that entire chunk of register as live/dead in suspend/restore, we can instead pattern-match the set of bytecodes in a suspend point, and propagate liveness across them. This tightens liveness estimates, and could be used to optimize which values TurboFan actually saves when suspending.

This is the V8 side change of crrev.com/c/876103. Message: It can happen that WebAssembly.compileStreaming gets aborted when we are not allowed to execute JavaScript code, and therefore are also not allowed to reject the promise returned by WebAssembly.compileStreaming. This can happen e.g. when the Chrome tab gets refreshed, which aborts all downloads. With this CL we do not pass a reason to Abort if we are not allowed to execute JavaScript code. On the V8 side we can check the reason passed to Abort and do not reject the promise if there is no reason passed.
