This makes the heuristic for computing the number of parallel tasks in Scavenger consistent with that in Mark-Compactor. The patch helps mobile devices where even 1 MB new space can take 10ms to scavenge.

This removes two unneeded casts and an unused parameter. Note that according to the specification, {Allocator}s need to provide an {allocate} method receiving the size {n}, and *optionally* they can support {allocate} with a second pointer parameter which they can use in an unspecified manner. Since we do not use the second argument, we should just not provide that method. Drive-by: Remove else-after-return.

This CL aims to address the regressions that we saw in Octane 2.1, particularly in the DeltaBlue test. This CL brings a 5% improvement in said test by doing CompressedSigned -> Word32 conversion (instead of CompressedSigned -> TaggedSigned -> Word32). There seems to be room for optimizations doing more specialized conversions regarding representation changes.

This adds a test case for using constructed {WebAssembly.Function} objects in non-zero tables. Due to a recent refactoring that unifies handling of dispatch tables, this works out of the box. The test coverage however is still useful, since code paths are slightly different for non-zero tables.

Cpplint usually checks for non-const reference arguments. They are forbidden in the style guide, and v8 does not explicitly make an exception here. This CL re-enables that warning, and fixes all current violations by adding an explicit "NOLINT(runtime/references)" comment. In follow-up CLs, we should aim to remove as many of them as possible.

This CL mitigates the worst performance regressions for stack trace symbolization. The first fix is to hold the StackFrameBase instance in a local variable. The instance is produced by an iterator but newly created everytime FrameArrayIterator::Frame is called. The second fix is to skip symbolization of "MethodName" and "TypeName" for non-method calls.

This CL teaches the deoptimizer about JavaScriptBuiltinContinuation frames that are not preceded by argument adapter frames. This pattern is used when calling C++ API functions from TurboFan. This CL fixes a crash when the deoptimizer encounters the pattern described above. The crash was caused when the deoptimizer tried to read the arguments of the continuation frame. As no adapter frame was present, the argument count was read from the SharedFunctionInfo which had the kDontAdaptArgumentsSentinel value. This translated to an argument count of ~65000 later down the line, which caused a FATAL error when the deoptimizer tried to re-construct ~65000 non-existent values.
