C compilation errors on builtin module

[ellxor]

The functions in the builtin module produce a C compilation error as they are defined to return u8, but the C __builtin_xxx equivalents return int. The forward declaration produced results in a type mismatch.

Minimal example to reproduce:

module example;
import builtin as b;

public fn i32 main(i32 argc, char **argv) {
    return b.popcount(cast<u32>(argc));
}

This gives an error with clang and a warning and link error with GCC.

Hi @ellxor, thank you for the feedback.
This is a bug, I shall try and fix the prototypes.
