    [wasm] Introduce a WasmTableInit CSA builtin · ca5ee9d6
    Andreas Haas authored
    This CL introduces a CSA builtin for the TableInit 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.
    
    The CL also introduces a small CSA function which takes an uint32 value
    and a max value as parameters and returns a Smi of the minimum of these
    two.
