    [wasm-simd] Fix OpcodeLength of load splat/extend ops · a67a16aa
    Ng Zhi An authored
    Move load splat and load extend ops into the list of SIMD memory
    opcodes, since they similarly take an i32 and an memarg. This fixes the
    OpcodeLength calculation in function-body-decoder-impl.h.
    
    And in turn, fixes the mjsunit test code that the fuzzer generates. See
    the regress-1055692.js file for the weird S8x16LoadSplat followed by 2
    kExprUnreachable, where the kExprUnreachable really is a memarg
    {0x0, 0x0}. This bug was caught by the fuzzer, and that was the
    generated test (with small fixes to add kExprDrop), so leaving it as it
    is.
