    [builtins] Port GetArgumentsFrameAndCount to Torque · a74afec6
    Daniel Clifford authored
    In the process, add the bint type (which stands for Best-INTeger),
    which implements Torque's idea of CSA's ParameterMode. It maps to
    a different type on 32-bit (Smi) and 64-bit (intptr). There are
    convert operators that are either no-ops or conversions
    to-and-from Smi and intptrs on the each platform, depending on
    the underlying type for bint. This allows Torque code to git most
    of the benefits of ParameterMode without having to explicitly
    pass around the mode, since it is almost always OptimalMode anyways.
