In preparation for adding more builtins, factor out the handling of builtin function kinds into separate files. Add checking for builtin function signatures. The mechanism used here is intended to provide a lot of flexibility for declaring generic builtin functions and pretty arbitrary constraints on the types of parameters of builtin functions. For now, these constraints are checked when the builtin function is declared. The hope is that this will suffice, but if not, it should be straightforward to switch to doing some of the checking on call and share logic between the checks. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com> Co-authored-by: Carbon Infra Bot <carbon-external-infra@google.com>
