There is not really a reason to guard the first by the latter. Just emit a hint if --trace-liftoff is used without --trace-wasm-decoder, but still make it work. Also, used DEFINE_DEBUG_BOOL instead of guarding the output by another "#ifdef DEBUG".

This fixes a few issues: 1) It avoids using the {DeserializeOrCompile} API method, which is not used in chrome any more and will be deprecated soon. 2) It switches to the {DeserializeNativeModule} internal method, which really checks deserialization in isolation and does not fall back to compiling the wire bytes if the serialized bytes are incorrect. 3) It disables a test which tried to invalidate the number of functions, but the respective bytes were already zero, so nothing was invalidated. This still needs to be fixed in a follow-up CL. 4) It serializes the modules in a separate isolate, which then gets disposed to free references to the NativeModule and remove it from the modules cache. Otherwise we will just never deserialize, but use the cached module instead.

This will be more expected for gasm users, since no other builders require such a Build() call.

The verifier tried to assert that the context input of Create*Context nodes has type OtherInternal (all Context constants have that type). This didn't quite work because of OSR values so actually it checked something much weaker. And what it checked still doesn't work because of dead code, in which the context input might statically be known to be the undefined value. I'm removing the assertion entirely now. I suspect that there are other assertions in the verifier that don't hold in the OSR code or in dead code. We are discussing a more general solution such as inserting TypeGuards in the relevant cases.

When bytecode is flushed we also want to flush the feedback vectors to save memory. There was a bug in this code and we flushed ClosureFeedbackCellArray too. Flushing ClosureFeedbackCellArrays causes the closures created by this function before and after the bytecode flush to have different feedback cells and hence different feedback vectors. This cl fixes it so we only flush feedback vectors on a bytecode flush. Also this cl pretenures ClosureFeedbackCellArrays. Only FeedbackCells and FeedbackVectors can contain ClosureFeedbackCellArrays which are pretenured, so it is better to pretenure ClosureFeedbackCellArrays as well.

This CL adds a new event that enables the back-end to send coverage updates on its own initiative. This event can be triggered via the C++ method `triggerPreciseCoverageDeltaUpdate` on the agent in a way that causes coverage data to be immediatelly collected. This is useful in the back-end to collect coverage at a certain point in time, i.e. when a lifecycle event such as first contentful paint occurs. The previous interface could not support this, because it could not reasonably be triggered from C++, and if triggered through the protocol, dispatching messages added delay that invalidated the data (i.e. data might have been taken too late to be accurate).

The loop peeling optimization requires all loop exits to be marked with {LoopExit,LoopExitEffect,LoopExitValue} nodes in order to peel the first loop iteration. Previously, the graph assembler only marked the default loop exit (taken once the loop condition evaluates to false). This CL adds more general support, such that all exits taken inside the loop body passed to a ForBuilder are automatically marked. We do this by tracking the current loop nesting level and a stack of loop headers inside the graph assembler, and creating marker nodes as needed inside MergeState.
