@min and @max should allow any number of arguments and notice integer bounds

[andrewrk]

const std = @import("std");

test "three arguments to @min" {
    var runtime1: usize = 1 << 17;
    const max_ciphertext_len = (1 << 14) + 256;
    var runtime2: u64 = 1 << 33;
    const ciphertext_len: u16 = @min(runtime1, max_ciphertext_len, runtime2);
    try std.testing.expect(ciphertext_len == max_ciphertext_len);
}

This test is expected to pass. Note that there should be no compile error due to coercion to u16 despite the use of runtime-known u64 and usize, because one of the arguments to @min is compile-time known to be within range of u16.

will there be other variadic functions or a way to define variadic functions (of comptime-known length, unlike in C)?

No. Language builtins are special.

There are archs with instructions for 3-way min, so this is a good call 👍

I guess there could be other builtins, but i can think of none where this applies

@TypeOf accepts any number of arguments
