    [wasm] Introduce a TableCopy builtin · 1e1d4d82
    Andreas Haas authored
    This CL introduces a CSA builtin for the TableCopy instruction. This
    builtin allows to generate smaller code for both TurboFan and Liftoff,
    and easier code generation from Liftoff.
    
    The smaller code size comes from:
    * Parameters are passed through registers, not the stack.
    * Lower number of parameters: the call target, number of parameters, and
    context are not passed as parameters.
    * No int to smi conversion in generated code.
