Fold distinct MUL and ADD (or SUB) instructions into a single MLA (or MLS) instruction, mirroring what is being done for general purpose registers. SIMD wasm only uses the vectorized ADD and MUL instructions on quad vectors (NEON Q), so only those cases are handled. SIMD wasm only uses MUL by vectors, not by elements so there is no need to check for an addition and shift reduction.

The native context independent (NCI) code variant will be used to test various aspects as the NCI implementation progresses. Examples: - Test js-generic-lowering with feedback collection. - Test NCI codegen without caching or tier-up. - Test NCI codegen and tier-up without caching. - Test full NCI (codegen, caching, tier-up). At some point a build-time flag may be required, we'll see when we get there. This variant should be removed once work on NCI is complete.

Liftoff code generated for debugging has an extended function prologue which checks the "hook on function entry" flag on the isolate. Because of this, code positions between standard Liftoff code and Liftoff code for debugging do not match up. When (lazily) generating debug side tables, we always generate them for debugging-flavored Liftoff code. The issue that this CL fixes happened when we tried to inspect non-debug Liftoff code, and lazily generated the debug side table for that code. As noted above, source positions would not match up in that case, and we get DCHECK failures (or crashes in release builds) when inspecting the code. This issue was uncovered as part of the multi-threaded debugging effort, but because of the similarity in the stack trace, it might also fix the other issues linked below. We will get test coverage as soon as we add multi-threaded debugging tests (which are in development, but are still hitting other issues).

This CL adds 2 new values to the EmbedderStackState enum with more explicit names. The old values are updated as aliases to the new values and marked as soon to be deprecated. This CL also moves the enum to v8-platform.h so that it can be reused by cppgc. Depracating individual values in an enum is supported by GCC only since version 6. Thus new macros were needed for the deprecation (which delegate to the existing macros when supported). GCC versions older than 6 are still used by the CQ bots.

We don't yet support serialization of optimized code, so whenever the serializer encounters an 'unexpected' Code object, it aborts. Snapshot::ClearReconstructableDataForSerialization does not clear weak links created through compilation dependencies. These links make Code objects reachable even though recompilable data has been cleared from JSFunctions/SFIs/JSRegExps. Forcing a full deopt of the entire isolate is the simple of way of solving this until serialization support for optimized code has been implemented.
