The current code for AssignRegisterOnReload starts the search at the first interval instead of relying on the cached {current_interval_}, which seems to be a main cause for slow compile time in the linked issue's test case. Moreover, it does not take into account live range holes of the current range. This change uses FirstIntersection instead which already handles both issues. Since inactive ranges are sorted by their next start, we can also break early from the loop.

Bitmask requires wasm_simd_post_mvp because it was merged into SIMD proposal after 84 cut, which Origin Trial starts. For now, bitmask is the only instruction that requires this flag to be set, and no other post mvp instructions are included in the fuzzer. We should revert this change (and also move bitmask out of the flag) after this OT is over.

This retrieves script name directly from StackFrameBase, bypassing building of StackFrameInfo if one hasn't already been initialized, thus avoiding computation of expensive properties that are not required. This matches current behavior of GetScriptNameOrSourceURL() and is a workaround until a dedicated API is available.

Local type information was stored in the {WasmFullDecoder}, and a pointer to that vector was handed to {WasmDecoder}. Since {WasmFullDecoder} inherits from {WasmDecoder}, we can just move the vector to the {WasmDecoder} class, and save an indirection and an unnecessary nullptr check. Drive-by: Rename {GetLocalType} to {local_type}, since it's a simple accessor. Drive-by 2: Move fields of {WasmDecoder} to the end of the class, as mandated in the style guide. Drive-by 3: Rename some locals in the 'let' decoding to make the meaning more clear.

Currently the FeedbackVector uses arrays in slots that are polymorphic, usually in a <map, handler> tuple pattern. Helper functions try to re-use an existing array if it's already in place. For Concurrent TurboFan, it would be far better if these FixedArrays were immutable. We could then count on semantic correctness when harvesting their information from a background thread without locking. Additionally, the arrays should always be initialized fully before being set in place.

Move more logic into the {TraceLine} class. In release builds, this class will not do anything. Since there is no code after the switch in {DecodeOp} any more after this CL, we can apply tail-call optimization (via explicit returns in C++), which will save an additional call in some cases.

Every condition which can only fail on invalid wire bytes should be wrapped in the VALIDATE macro. This way, it will automatically be skipped if {validate} is false, and we will automatically add V8_LIKELY annotations to the branches. Also, consistently use the style if (!VALIDATE(condition)) { ... handle error ... } ... continue ... Drive-by: Remove unnecessary OPCODE_ERROR macro. Drive-by 2: Replace unreachable code (after a switch) by UNREACHABLE.

V8 fails a recently added spec test that when an imported global get re-exported, it should preserve its identity. This CL fixes the behavior in V8. Drive-by change: fix the object printer of globals: a global which stores a reference type only has a tagged buffer, a global which stores a value type only has an untagged buffer.
