PPC Simd regs are already using separate set of register banks on ppc, more details can be found here: https://crrev.com/c/2718472 Here we are making use of this CL https://crrev.com/c/3005768 (fcd3ef48) and fully separating Simd regs during register allocation. Member function `toSimd()` is also introduced which will be used to cast FP regs to Simd regs in liftoff.

The current compression scheme defines isomorphism with respect to relational operations (i.e. the relational operators preserve their results on the set of compressed pointers). In addition, provide overloads for nullptr/sentinel.

The increase caused a significant PMF regression on Windows. Apparently, leaving the table in reserved state didn't eliminate the regression. The CL returns the age size back to 1MB. The followup is to investiage and fix the regression.

The operator with raw pointer allows us to avoid Member decompression, which is more expensive than compression. It's also quite frequently called (e.g. in HeapHashSet::find()). The existing operator template <...> bool operator==(const Member<T1>&, const Member<T2>&); was not called for GCed* raw = ...; member == raw; because the compiler wouldn't deduce `T2` in `const Member<T2>` as `GCed` when the initializer expression `raw` is of different type (`GCed*`).

Implements an initial prototype of the Wasm Trace proposal. A custom section containing offsets to functions is decoded into trace instructions that are inserted into the function. In Liftoff, these are directly inserted. In TurboFan, these are added as StackEffect's, this is a work in progress. Traces will only be decoded and added when a flag is given to V8, currently "--experimental-wasm-instruction-tracing". If a trace is ever not valid or an error occurs, it is safe to just throw them away.

V8 was compiled for Fuchsia with optimize_speed instead of optimize_max used on most other platfroms. There is no reason Fuchsia needs to be different, so it's better to use optimize_max. It also allows to save about 1MB on the binary size.

The exact method name is not interesting when looking at crash statistics, and can easily be retrieved from stack traces. Instead, print a consice string saying what we were trying to do when we ran OOM. This is more consistent with other OOM location strings.

It is not safe to allocate ExternalPointerTable entries while the table is being swept. This property is currently ensured by the GC. To better catch any potential future violation of this requirement, this CL now changes the Sweep() method to first set the freelist head to a special marker value, which is checked in Allocate() in debug builds and will cause a recognizable crash in release builds.
