We've been building up this exponential explosion of task-creation builtins because it's not currently possible to overload builtins. As long as all of the operands are scalar, though, it's pretty easy to peephole optional injections in IRGen, which means we can at least just use a single builtin in SIL and then break it apart in IRGen to decide which options to set. I also eliminated the metadata argument, which can easily be recreated from the substitutions. I also added proper verification for the builtin, which required (1) getting `@Sendable` right more consistently and (2) updating a bunch of tests checking for things that are not actually valid, like passing a function that returns an Int directly.
