This replaces VisitMode with a set of option flags that allow skipping specific roots like unserializable, weak, global handles, etc. The advantage is that it is no longer coupled with the callers and does not know about different types of GCs and their phases. The CL is pure refactoring without behavior changes except for the heap verification where more roots are verified that before.

In the existing code we used a register of the UseScratchRegisterScope for the destination address. However, this register is needed for the ParallelRegisterMove as well. With this CL we use fixed registers for the destination address and the offset as well. The CL also changes the implementation of CalculateActualAddress to allow to set an explicit register for the result.

This patch implements f32x4.pmin, f32x4.pmax, f64x2.pmin, and f64x2.pmax for x64 and interpreter. Pseudo-min and Pseudo-max instructions were proposed in https://github.com/WebAssembly/simd/pull/122. These instructions exactly match std::min and std::max in C++ STL, and thus have different semantics from the existing min and max. The instruction-selector for x64 switches the operands around, because it allows for defining the dst to be same as first (really the second input node), allowing better codegen. For example, b = f32x4.pmin(a, b) directly maps to vminps(b, b, a) or minps(b, a), as long as we can define dst == b, and switching the instruction operands around allows us to do that.

This started as fixing a clang-tidy warning to use a explicitly defaulted destructor, see https://chromium.googlesource.com/chromium/src/+/HEAD/styleguide/c++/c++-dos-and-donts.md#prefer-to-use. But we can clean it up a bit more to omit the destructor, since the all its members are trivially destructible. With this change, ByteData is now is_trivially_destructible.

This changes the existing implementation that creates an unresolved reference for those cases to look at exactly what scopes are relevant so it can correctly handle catch scopes and avoid re-resolving later. Variable through with aren't marked as assigning since this information isn't relevant for the with itself; and if the with is passed through, there's no need to mark the outer variable as assigned since it's either initialized or it isn't. The catch variable is assigned since it is relevant for the catch variable. The CL uses LookupLocal which wouldn't work for deserialized scopes, but this isn't relevant because 1) eval scopes are declaration scopes, and 2) eval causes all outer variables to be maybe_assigned anyway.

This patch provides infrastructure to pin object types to specific spaces. This allows embedders to create mutual exclusive arenas for certain (base) types. In future, this will also be used to provide sliding-window compaction on certain custom spaces. We mainly preserve the existing infrastructure with the difference that spaces are now slightly more dynamic than in Blink as they are kept in a vector instead of a fixed-size array. The mechanism differs from Blink in that it does not allow the user object to call allocation methods directly but instead provides a trait that can be overridden to specify a custom space. The patch preserves templatization for objects that do not go into custom spaces to safe a branch in the allocation hot path.
