Reviewed by Justin Michaud.

This patch implements wasm Tuple including V128 constant.
To make it work,

1. We extend Bottom value generation to support V128.
2. We add B3 IR generator constant with 0xbbadbeef generation for V128.

* JSTests/wasm/stress/resources/tuple-and-v128.wasm: Added.
* JSTests/wasm/stress/tuple-and-simd.js: Added.
