The asm.js offset table exists in two forms: Delta-encoded in a byte array, as generated during asm translation, and decoded, for faster lookup. This CL moves the encoded version from the {AsmWasmData} and {WasmModuleObject} to the {WasmModule}, and stores it off-heap in a C++ array instead of a {ByteArray}. Also, it moves the decoded version off-heap by storing it in a C++ data structure that makes lookup easy, instead of encoding it again in another {ByteArray}. This change is a nice refactoring in itself, but it also prepares adding more information to the offset table. For reconstructing the source code of an asm.js function, we will need to store the start and end offsets of the whole function as well (see linked bug).

The test was supposed to manipulate the serialized bytes to make them invalid, but the value at the manipulated position was already 0, hence the bytes stayed valid. This went unnoticed before https://crrev.com/c/2010786, since there was a fallback anyway to re-compile the module if deserialization fails. This CL fixes this by using the right offset, and checking that the value there is not already zero.

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.

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).
