Summary [WASM] Fix prefixed-opcode code origins for relaxed SIMD opcodes

https://bugs.webkit.org/show_bug.cgi?id=277089 assumes that the remaining part of a prefixed opcode fits in a single byte, which it turns out the most recent version of the relaxed-SIMD proposal violates, with opcodes between 0x100 and 0x12F. We should fix this since on 64-bit platforms at least we have bits to spare to store a larger opcode.
