    [wasm-simd] Fix bounds check for load extends · a85b5a63
    Ng Zhi An authored
    Load extends always load 8 bytes, so the access size does not depend on
    MachineType of the load. The MachineType is used for classifying the
    lane shape of the 8-byte load.
    
    Also add cctest to load splats and load extends to test OOB. (Note that
    load splats access size depends on MachineType).
    
    Add regression test from clusterfuzz, minimized by ahaas@. Remove the
    `--no-wasm-trap-handler` flag since we have a no_wasm_traps variant that
    should test this flag.
