- Eliminates b1x4, b1x8, and b1x16 as distinct WASM types.
- All vector comparisons return v128 type.
- Eliminates b1xN and, or, xor, not.
- Selects take a v128 mask vector and are now bit-wise.
- Adds a new test for Select, where mask is non-canonical (not 0's and -1's).

- 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.

MachineType is now a class with two enum fields:
- MachineRepresentation
- MachineSemantic

Both enums are usable on their own, and this change switches some places from using MachineType to use just MachineRepresentation. Most notably:
- register allocator now uses just the representation.
- Phi and Select nodes only refer to representations.

This is the bare minimum required to support typed arrays. Support for
working with float32 values will be added based on this.

MachineType now tracks both the representation and the value type of machine quantities and is used uniformly throughout TurboFan.

These types can now express uint8, int8, uint16, and int16, i.e. signed and unsigned smallish integers. Note that currently only uint8 and uint16 are implemented in the TF backends.
