[V8] Implement SIMD Boolean vector types to allow mask registers. - Adds new machine types SimdBool4/8/16 for the different boolean vector types. - Adds a kSimdMaskRegisters flag for each platform. These are all false for now. - Removes Create, ExtractLane, ReplaceLane, Equal, NotEqual, Swizzle and Shuffle opcodes from the Boolean types. These are unlikely to be well supported natively, and can be synthesized using Select. - Changes the signature of Relational opcodes to return boolean vectors. - Changes the signature of Select opcodes to take boolean vectors. - Updates the ARM implementation of Relational and Select opcodes.
